Hive configuration with Spark
Hive on Spark gives Hive the capacity to use Apache as its execution motor. We will be using the following steps to configure Hive:
- Copy hive-site.xml to the Spark configuration folder as follows:
cp $HIVE_HOME/conf/hive-site.xml $SPARK_HOME/conf/
- Add the following line to ~/.bash_profile:
export SPARK_CLASSPATH=$HIVE_HOME/lib/mysql-connector-java-3.1.14-bin.jarsource ~/.bash_profile
- Run the following command to access Spark SQL:
spark-sql
Check for existing databases and tables with the Show Databases and Show Tables commands. You'll find all of the databases and corresponding tables that you have in Hive.
