Ah, sorry:) Yes, here you can't specify driver related parameters using <spark-opts>--driver-memory 10g</spark-opts> because your driver (oozie launcher job) is already launched before that point. It's a oozie launcher (which is a mapreduce job) launches your actual spark job and so spark-opts is not relevant. But the Oozie spark action doc says: The configuration element, if present, contains configuration properties that are passed to the Spark job. This is shouldn't be spark configuration. It should be mapreduce configuration for launcher job. So, please try to add the following <configuration> <property> <name>oozie.launcher.mapreduce.map.memory.mb</name> <value>4096</value> </property> <property> <name>oozie.launcher.mapreduce.map.java.opts</name> <value>-Xmx3072m</value> </property> </configuration> ...
