(Updated Nov. 8, 2013, 10:50 p.m.) Review request for oozie. Changes ------- Review changes. Bugs: OOZIE-1584 https://issues.apache.org/jira/browse/OOZIE-1584 Repository: oozie Description ------- Supported features. ----------------- 1. If Oozie.action.ship.launcher.jar = true then, Oozie auto-deploy jar at server start. 2. Admin copies sharelib to new timestamp directory and issues invalidate command to Oozie server. Oozie picks latest shared lib. 3. Oozie server doesn't auto deploy sharelib at startup. It picks the latest sharelib jar pushed by admin(based on timestamp). 4. Sharelib mapping files. Sharelib mapping file can be also configured.Configured file is a key value mapping, where key will be the action and value is DFS directory of sharelib files for action. This can be configured in oozie-site.xml as : <property> <name>oozie.service.ShareLibService.mapping.file</name> <value></value> <description> Sharelib mapping files contains list of key=value, where key is the action key and value is the DFS location of sharelib files. </description> </property> -------------------- DFS after generating launcher jar by ooozie server and sharelib by cli makebag-lm:example purushah$ /var/hadoop-1.2.1/bin/hadoop fs -ls /user/purushah/share/lib/ /user/purushah/share/lib/launcher_20131017092254 /user/purushah/share/lib/launcher_20131017093814 /user/purushah/share/lib/launcher_20131017094652 /user/purushah/share/lib/launcher_20131017094836 /user/purushah/share/lib/launcher_20131017095549 /user/purushah/share/lib/lib_20131017092806 makebag-lm:example purushah$ Purging. ------------- There are two set( launcher_ for launcher jars and Lib_ for shared lib) of directory and purging happens for both at startup. Anything older than ( defined in property) is purged. We always keep 2 set of directory, purging happens if number of sharelib directory > 2. Multiple version. ------------------- To support multiple version, sharelib will be in below format. Sharelib will cache all versions and return list of dfs files for a particular version. makebag-lm:example purushah$ /var/hadoop-1.2.1/bin/hadoop fs -ls /user/purushah/share/lib/ Found 15 items /user/purushah/share/lib/launcher_20131017092254 /user/purushah/share/lib/launcher_20131017093814 /user/purushah/share/lib/launcher_20131017094652 /user/purushah/share/lib/launcher_20131017094836 /user/purushah/share/lib/launcher_20131017095549 /user/purushah/share/lib/lib_20131017092806/pig/... /user/purushah/share/lib/lib_20131017092806/pig_9/... /user/purushah/share/lib/lib_20131017092806/pig_10/... makebag-lm:example purushah$ Diffs (updated) ----- http://svn.apache.org/repos/asf/oozie/trunk/core/src/main/java/org/apache/oozie/action/hadoop/JavaActionExecutor.java 1532127 http://svn.apache.org/repos/asf/oozie/trunk/core/src/main/java/org/apache/oozie/service/ShareLibService.java 1532127 http://svn.apache.org/repos/asf/oozie/trunk/core/src/main/resources/oozie-default.xml 1532127 http://svn.apache.org/repos/asf/oozie/trunk/core/src/test/java/org/apache/oozie/service/TestShareLibService.java 1532127 http://svn.apache.org/repos/asf/oozie/trunk/docs/src/site/twiki/AG_Install.twiki 1532127 http://svn.apache.org/repos/asf/oozie/trunk/docs/src/site/twiki/DG_QuickStart.twiki 1532127 http://svn.apache.org/repos/asf/oozie/trunk/tools/src/main/java/org/apache/oozie/tools/OozieSharelibCLI.java 1532127 Diff: https://reviews.apache.org/r/14741/diff/ Testing ------- Thanks, Purshotam Shah
