java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

I have Hadoop 2.7.1 and apache-hive-1.2.1 versions installed on ubuntu 14.0.

1. Why this error is occurring ?

2. Is any metastore installation required?

3. When we typing hive command on terminal how the xml's internally called, what is the flow of those xml's?

4. Any other configuration's required?

When I am writing the hive command on ubuntu 14.0 terminal it is throwing the below exception.

 $ hive

To avoid above error I created hive-site.xml with :

 <configuration>
    
      <property>
        <name>hive.metastore.warehouse.dir</name>
        <value>/home/local/hive-metastore-dir/warehouse</value>
        
      </property>
    
    <property>
      <name>javax.jdo.option.ConnectionURL</name>
      <value>jdbc:mysql://localhost:3306/hivedb?createDatabaseIfNotExist=true</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionDriverName</name>
      <value>com.mysql.jdbc.Driver</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionUserName</name>
      <value>user</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionPassword</name>
      <value>password</value>
    </property>
    
    <configuration>

Also provided the environment variables in ~/.bashrc file; Still the error persist

#HIVE home directory configuration
export HIVE_HOME=/usr/local/hive/apache-hive-1.2.1-bin
export PATH="$PATH:$HIVE_HOME/bin"

I did below modifications and I am able to start the Hive Shell without any errors:

1. ~/.bashrc

Inside bashrc file add the below environment variables at End Of File : sudo gedit ~/.bashrc

#Java Home directory configuration
export JAVA_HOME="/usr/lib/jvm/java-9-oracle"
export PATH="$PATH:$JAVA_HOME/bin"

# Hadoop home directory configuration
export HADOOP_HOME=/usr/local/hadoop
export PATH=$PATH:$HADOOP_HOME/bin
export PATH=$PATH:$HADOOP_HOME/sbin

export HIVE_HOME=/usr/lib/hive
export PATH=$PATH:$HIVE_HOME/bin

2. hive-site.xml

You have to create this file(hive-site.xml) in conf directory of Hive and add the below details

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>

<property>
  <name>javax.jdo.option.ConnectionURL</name>
  <value>jdbc:mysql://localhost/metastore?createDatabaseIfNotExist=true</value>
</property>


<property>
  <name>javax.jdo.option.ConnectionDriverName</name>
  <value>com.mysql.jdbc.Driver</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionUserName</name>
  <value>root</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>root</value>
</property>

<property>
  <name>datanucleus.autoCreateSchema</name>
  <value>true</value>
</property>

<property>
  <name>datanucleus.fixedDatastore</name>
  <value>true</value>
</property>

<property>
 <name>datanucleus.autoCreateTables</name>
 <value>True</value>
 </property>

</configuration>

3. You also need to put the jar file(mysql-connector-java-5.1.28.jar) in the lib directory of Hive

4. Below installations required on your Ubuntu to Start the Hive Shell:

1. MySql

2. Hadoop

3. Hive

4. Java

5. Execution Part:

1. Start all services of Hadoop: start-all.sh

2. Enter the jps command to check whether all Hadoop services are up and running: jps

3. Enter the hive command to enter into hive shell: hive

starting the hive metastore service worked for me. First, set up the database for hive metastore:

 $ hive --service metastore 

` https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.4/bk_installing_manually_book/content/validate_installation.html

Second, run the following commands:

 $ schematool -dbType mysql -initSchema  
 $ schematool -dbType mysql -info

https://cwiki.apache.org/confluence/display/Hive/Hive+Schema+Tool

If you're just playing around in local mode, you can drop metastore DB and reinstate it:

rm -rf metastore_db/
$HIVE_HOME/bin/schematool -initSchema -dbType derby

In my case when i tried

$ hive --service metastore 

I got

> MetaException(message:Version information not found in metastore. )

The necessary tables required for the metastore are missing in MySQL. Manually create the tables and restart hive metastore.

cd $HIVE_HOME/scripts/metastore/upgrade/mysql/ 

< Login into MySQL > 

mysql> drop database IF EXISTS <metastore db name>; 
mysql> create database <metastore db name>; 
mysql> use <metastore db name>; 
mysql> source hive-schema-2.x.x.mysql.sql; 

metastore db name should match the database name mentioned in hive-site.xml files connection property tag.

hive-schema-2.x.x.mysql.sql file depends on the version available in the current directory. Try to go for the latest because it holds many old schema files also.

Now try to execute hive --service metastore If everything goes cool, then simply start the hive from terminal.

>hive

I hope the above answer serves your need.

Run hive in debug mode

hive -hiveconf hive.root.logger=DEBUG,console

and then execute

show tables

can find the actual problem

I have used MySQL DB for Hive MetaStore. Please follow the below steps:

• in hive-site.xml the metastore should be proper

<property>
 <name>javax.jdo.option.ConnectionURL</name> 
 <value>jdbc:mysql://localhost/metastorecreateDatabaseIfNotExist=true&amp;useSSL=false</value>
</property>

• go to the mysql: mysql -u hduser -p
• then run drop database metastore
• then come out from MySQL and execute schematool -initSchema dbType mysql

Now error will go.

you just need to instantiate schema and you can do the same with the below commands.i dit it and am able to run hive query without throwing ERROR:Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

cd $HIVE_HOME
mv metastore_db metastore_db_bkup
schematool -initSchema -dbType derby
bin/hive

now run your query:

hive> show databases;

In the middle of the stack trace, lost in the "reflection" junk, you can find the root cause:

The specified datastore driver ("com.mysql.jdbc.Driver") was not found in the CLASSPATH. Please check your CLASSPATH specification, and the name of the driver.

mybe your hive metastore are inconsistent! I'm in this scene.

first. I run

 $ schematool -dbType mysql -initSchema  

then I found this

> Error: Duplicate key name 'PCS_STATS_IDX' (state=42000,code=1061) org.apache.hadoop.hive.metastore.HiveMetaException: Schema initialization FAILED! Metastore state would be inconsistent !!

then I run

 $ schematool -dbType mysql -info

found this error

> Hive distribution version: 2.3.0 Metastore schema version: 1.2.0 org.apache.hadoop.hive.metastore.HiveMetaException: Metastore schema version is not compatible. Hive Version: 2.3.0, Database Schema Version: 1.2.0

so i format my hive metastore, then it's done!

• drop mysql database, the database named hive_db
• run schematool -dbType mysql -initSchema for initialize metadata

This is probably due to its lack of connections to the Hive Meta Store,my hive Meta Store is stored in Mysql,so I need to visit Mysql,So I add a dependency in my build.sbt

libraryDependencies += "mysql" % "mysql-connector-java" % "5.1.38"

and the problem is solved!

I have also faced this problem but i had restart Hadoop and use command hadoop dfsadmin -safemode leave

now start hive it will work i think

I solved this problem by removing --deploy-mode cluster from spark-submit code. By default , spark submit takes client mode which has following advantage :

1. It opens up Netty HTTP server and distributes all jars to the worker nodes.
2. Driver program runs on master node , which means dedicated resources to driver process.

While in cluster mode :

 1.  It runs on worker node.
 2. All the jars need to be placed in a common folder of the cluster so that it is accessible to all the worker nodes or in folder of each worker node.

Here it's not able to access hive metastore due to unavailability of hive jar to any of the nodes in cluster.

just open the hive terminal from the hive folder,after editing (bashrc) and (hive-site.xml) files. Steps-- open hive folder where it is installed. now open terminal from folder.

In my case, I stopped my docker hive container and run it again and finally, it worked. Hope it will be useful for someone.

Note: This might be caused because there might be an instance running in the background so stopping the container will stop all background instances.

This is happening because you have NOT started the Hive Metastore ... the simples way to do that is to use the default Derby database one ... you can follow this link : https://sparkbyexamples.com/apache-hive/hive-hiveexception-java-lang-runtimeexception-unable-to-instantiate-org-apache-hadoop-hive-ql-metadata-sessionhivemetastoreclient/

I Fixed this Problem by creating and copying hive-default.xml.template to hive-site.xml. To create that use can use below commands

cd /usr/local/Cellar/hive/2.7.1/libexec/conf (please replace hive version)
cp hive-default.xml.template hive-site.xml

and changed the values of the below properties in hive-site.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
   <property>
      <name>javax.jdo.option.ConnectionURL</name>
      <value>jdbc:mysql://localhost/metastore?createDatabaseIfNotExist=true</value>

    <description>
      Expects one of the pattern in [mysql, postgresql, derby].
      Type of the metadata database.
    </description>
  </property>
</configuration>

After that, I created DB in MySql with the name matastore, created a usename password and grand permissions for it by using the following queries.

$ mysql
mysql> CREATE DATABASE metastore;
mysql> USE metastore;
mysql> CREATE USER 'hiveuser'@'localhost' IDENTIFIED BY 'password';
mysql> GRANT SELECT,INSERT,UPDATE,DELETE,ALTER,CREATE ON metastore.* TO 'hiveuser'@'localhost';

and run the script in MySql with the following command:

mysql> source /usr/local/Cellar/hive/3.1.2_3/libexec/scripts/metastore/upgrade/mysql/hive-schema-3.1.0.mysql.sql

Also don't forget to move SQL connector jar to hive package using the following commands Download MySQL connector and extract it

tar zxvf mysql-connector-java-5.1.35.tar.gz
sudo cp mysql-connector-java-5.1.35/mysql-connector-java-5.1.35-bin.jar /usr/local/Cellar/hive/2.7.1/libexec/lib/

That's it. Now I can successfully run show tables, etc commands in Hive. :)
