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:
- MySql
- Hadoop
- Hive
- Java
5. Execution Part:
- Start all services of Hadoop: start-all.sh
- Enter the jps command to check whether all Hadoop services are up and running: jps
- Enter the hive command to enter into hive shell: hive
