Enable to run Spark from OOZIE

New Contributor

Since cdh5.5.2 we are unable to run spark actions from oozie workflows, following error occures:


Failing Oozie Launcher, Main class [org.apache.oozie.action.hadoop.SparkMain], main() threw exception, EXTERNAL_PROPERTY


This is caused by jackson library which is bundled into spark-hive.jar and conflicts with some older version of jackson library thats part of oozie spark sharelib.
