Following changes were required: 1.) By default the pre-built distribution for Spark 2.2.0 is compiled with Scala 2.11. monasca-transform requires Spark compiled with Scala 2.10 since we use spark streaming to pull data from Kafka and the version of Kafka is compatible with Scala 2.10. The recommended way is to compile Spark with Scala 2.10, but for purposes of devstack plugin made changes to pull the required jars from mvn directly. (see SPARK_JARS and SPARK_JAVA_LIB variables in settings) All jars get moved to <SPARK_HOME>/assembly/target/assembly/ target/scala_2.10/jars/ Note: <SPARK_HOME>/jars gets renamed to <SPARK_HOME>/jars_original. spark-submit defaults to assembly location if <SPARK_HOME>/jars directory is missing. 2.) Updated start up scripts for spark worker and spark master with a new env variable SPARK_SCALA_VERSIOn=2.10. Also updated PYTHONPATH variable to add new py4j-0.10.4-src.zip file 3.) Some changes to adhere to deprecated pyspark function calls which were removed in Spark 2.0 Change-Id: I8f8393bb91307d55f156b2ebf45225a16ae9d8f4 |
