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

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
