[jira] [Commented] (OOZIE-308) GH-480: Support new Pig API to submit pig job

["Hadoop QA (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-308?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13099980#comment-13099980 ] 

Hadoop QA commented on OOZIE-308:
---------------------------------

brookwc remarked:
Pig team suggests Oozie to use the new API PigRunner.run() to submit and run Pig jobs. They do NOT plan to support use of Main.main(args) in Oozie in future. As such, we plan to adopt this new API. Also for backward-compatibility concern, we need to support old Pig version as well. 

Our proposal is as follows:
Oozie will check if new class/API is available on classpath through java reflection, if it is (Pig-0.8+), Oozie will use it. Otherwise Oozie will still use Main.main().

Your comments and thoughts are welcome.
