Spark integration with hive can be validated as follows:Īnother example to validate spark install using transformations Map and flatMap: You can validate the install by running the following commands: $ cp /Library/Java/Extensions/mysql-connector-java-5.1.46.jar $SPARK_JARS_DIR/ $ cp $HIVE_CONF_DIR/hive-site.xml $SPARK_CONF_DIR/
NOTE: $SPARK_CONF_DIR and $SPARK_JARS_DIR have been configured as part of the environment variables for spark.
in my case the MySQL JDBC driver into the $SPARK_JARS_DIR. In order to use Hive databases and tables in spark, we need to copy (or create symlinks to) the hive-site.xml into the $SPARK_CONF_DIR and also the hive metastore JDBC driver i.e. Once the brew formula is updated, run the install process using,Įxport SPARK_HOME=/usr/local/Cellar/apache-spark/2.2.1/libexec
Update the url, version and sha256 to the below, then save and exit: So we are good on that front.įirst up, brew edit apache-spark. Pre-reqs wise, only Java (6+) is required.
