Subject [jira] [Commented] (FALCON-141) Support cluster updates
Date Wed, 02 Dec 2015 04:58:11 GMT

    [ https://issues.apache.org/jira/browse/FALCON-141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15035271#comment-15035271

Venkat Ranganathan commented on FALCON-141:
-------------------------------------------

Thanks [~sriksun] for summarizing the thoughts.   The safemode approach is good.   In fact
we had talked about it internally and put up in a review after discussing with [~bvellanki]
and [~sowmyaramesh] also.   

Regarding the hadoop cluster and oozie order of migration, the rolling upgrade and express
upgrade (as ambari calls it - coming in next Ambari release) have some order of updates built
into them (and different pre-requisites) but manual upgrade might have different requirements.
  So, it would be good to discuss these scenarios separately and see how the cluster update
feature will work with them
