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

Question

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      Logging initialized using configuration in jar:file:/usr/local/hive/apache-hive-1.2.1-bin/lib/hive-common-1.2.1.jar!/hive-log4j.properties     Exception in thread "main"

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" 

Answer 1

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
