Subject [jira] [Updated] (YARN-2837) Timeline server needs to recover the timeline DT when restarting
Date Tue, 02 Dec 2014 04:56:13 GMT

     [ https://issues.apache.org/jira/browse/YARN-2837?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhijie Shen updated YARN-2837:
------------------------------
    Attachment: YARN-2837.3.patch

Create a new patch to suppress the findbugs warning. The reason is that KeyParser will only
be used internally, and I just copy and paste it to refactor the code. While deep copying
may solve the warning, it will unnecessarily downgrade the performance.

> Timeline server needs to recover the stateful information when restarting as RM/NM/JHS
does now. So far the stateful information only includes the timeline DT. Without recovery,
the timeline DT of the existing YARN apps is not long valid, and cannot be renewed any more
after the timeline server is restarted.
