Subject [jira] [Commented] (YARN-1809) Synchronize RM and Generic History Service Web-UIs
Date Fri, 27 Feb 2015 23:04:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-1809?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14340984#comment-14340984

Xuan Gong commented on YARN-1809:

bq.In ApplicationHistoryClientService, make sure we don't change the implementation of getApp/AttemptContainer(s).


bq. ApplicationHistoryManagerImpl doesn't need to be changed. It's already deprecated.


bq.Why is the following code removed? It may result in page exception if the following checks
are not done.


bq. In AppAttemptBlock.java, we need to the similar change that we did in AppBlock.java to
check the case that the tracking url == N/A.


bq. Since we excluded the change of scheduler webpage, isFairSchedulerPage is no longer necessary
in WebPageUtils.

Looks like we still need this. 
-  protected String getAppsTableColumnDefs() {
-    StringBuilder sb = new StringBuilder();
-    return sb
-      .append("[\n")
-      .append("{'sType':'string', 'aTargets': [0]")
-      .append(", 'mRender': parseHadoopID }")
-      .append("\n, {'sType':'numeric', 'aTargets': [5, 6]")
-      .append(", 'mRender': renderHadoopDate }")
-      .append("\n, {'sType':'numeric', bSearchable:false, 'aTargets': [9]")
-      .append(", 'mRender': parseHadoopProgress }]").toString();
We removed this code from RmView.java and added a more generic one in WebPageUtils

bq. AHS web services has been changed in this patch too. I did quick check, and it seemed
to work too. Please double check as well.

> After YARN-953, the web-UI of generic history service is provide more information than
that of RM, the details about app attempt and container. It's good to provide similar web-UIs,
but retrieve the data from separate source, i.e., RM cache and history store respectively.
