Ryota Egashira commented on OOZIE-1461: --------------------------------------- one motivation is performance enhancement. in 1), launcher jar is created and uploaded per action everytime, and it adds up delay in starting action, and execution time of workflow. this is critical for some of application which are time-sensitive. sharelib is one solution, but due to known issue already mentioned, we'd like to have option to upload to temp directory instead of sharelib. > provide an option to auto-deploy launcher jar onto HDFS system libpath > ---------------------------------------------------------------------- > > Key: OOZIE-1461 > URL: https://issues.apache.org/jira/browse/OOZIE-1461 > Project: Oozie > Issue Type: Bug > Affects Versions: trunk > Reporter: Ryota Egashira > Assignee: Ryota Egashira > Fix For: trunk > > > after OOZIE-1311, 1315, when oozie.action.ship.launcher.jar is false, > launcher jar is shipped from sharelib, but it requires manual process for > admin people to upload jar files onto the sharelib at server-start time, > before actually starting running workflow actions. This JIRA to provide an > option to remove the manual process, and make oozie server (ActionService) to > automatically create and upload launcher jar files onto HDFS (tmp directory > under oozie.service.WorkflowAppService.system.libpath), and allow workflow > actions to consume from there. every time oozie server starts, it > automatically creates a new directory to upload launcher jars to, and also > purges stale directories previously created (older than 7 days, > configurable). > if false (which is current default). the behavior is the same with previous, > launcher jars provided from sharelib (when > oozie.action.ship.launcher.jar=false) or each workflow action creates and > ships launcher jar (when oozie.action.ship.launcher.jar=true) -- This message is automatically generated by JIRA.
