Subject [jira] [Commented] (AMBARI-14949) Ambaripreupload should skip uploading oozie shared lib for upgrade
Date Fri, 05 Feb 2016 22:28:39 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-14949?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15135161#comment-15135161
] 

Andrew Onischuk commented on AMBARI-14949:
------------------------------------------

1.
{noformat}
+  parser.add_option("-u", "--upgrade", dest="upgrade", action="store_true",
+                    help="flag to indicate script is being run for upgrade", default=False)

{noformat}
If -v is specified this is upgrade else it's not (and the current version is taken).  This
is the way we designed this in the first place.

2.
{noformat}
+  if options.upgrade:
+    Logger.info("Skipping uploading oozie shared lib during upgrade")
+  else:
+    raise Exception("Incorrect Logic!")
{noformat}
Also unsure if we need to raise exception here.

> In syspreped clusters, while running RU Oozie service checks before upgrade Oozie will
fail
> This is because Ambaripreupload will overwrite the old version oozie shared lib in HDFS
with new version.
> We should add additional flag (--upgrade) to skip uploading oozie shared lib when Ambaripreupload
needs to be run before upgrades.
