Peter Bacsko reassigned OOZIE-2687: ----------------------------------- Assignee: Peter Bacsko > OYA: Figure out how to handle MR-specific properties > ---------------------------------------------------- > > Key: OOZIE-2687 > URL: https://issues.apache.org/jira/browse/OOZIE-2687 > Project: Oozie > Issue Type: Sub-task > Reporter: Peter Cseh > Assignee: Peter Bacsko > > It was possible to manipulate the MapperLauncher's environment through > properties like: > # mapreduce.map.memory.mb > # mapreduce.map.cpu.vcores > # mapred.child.env > # mapred.child.java.opts > # mapred.job.queue.name - ability to set launcher queue > E.g. We were using mapred.child.env to pass SPARK_HOME to the LauncherMapper > and make PySpark work. > Fixing OOZIE-2596 added a hack. We should decide how we support or break > compatibility and how we allow the manipulation of the Launcher environment. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
