[jira] [Commented] (OOZIE-2522) There can be multiple coord submit from bundle in case of ZK glitch

    [ https://issues.apache.org/jira/browse/OOZIE-2522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15314770#comment-15314770 ] 

Rohini Palaniswamy commented on OOZIE-2522:
-------------------------------------------

Changes to SharelibService do not belong to this patch. Please revert it. 

bq. //Not throwing exception. Should return null, so that command can be requeued
  Won't this cause commands to be requeued repeatedly in a loop if there is issue for a longer time and cause queue overflow?

bq. the patch seems to introduce 1 new javac warning(s)
  Please look into and fix this one.

> Bundle queue coord submit command to create coord job. 
> CoordSubmitXCommand doesn't acquire any lock. CoordSubmitXCommand inserts entries to DB and calls BundleStatusUpdateXCommand to update bundle action. At the same time, if there is any ZK glitch, BundleStatusUpdateXCommand will fail ( because it needs to acquire lock) and RecoveryService will submit duplicate jobs.
