Subject [jira] [Commented] (MAPREDUCE-5934) Make JHS source the timeline server for job history information
Date Thu, 19 Jun 2014 02:12:24 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5934?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14036848#comment-14036848

Zhijie Shen commented on MAPREDUCE-5934:
----------------------------------------

I'm thinking that we should not default the current JHS stack immediately, as it may break
existing users. We can gradually deprecate it given JHS on the timeline server becomes stable.
 What we can do now is to have a configure to switch between HDFS backup or timeline server
backup. If the user configure to use the timeline server as the data source, he is supposed
to start the timeline server.
