Subject [jira] [Commented] (YARN-2890) MiniMRYarnCluster should turn on timeline service if configured to do so
Date Wed, 26 Nov 2014 18:50:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-2890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14226633#comment-14226633

Zhijie Shen commented on YARN-2890:
-----------------------------------

Thanks for the patch, Mit!

1. It makes sense to rely on the config to determine if we want to start the timeline server
in mini YARN cluster. If we're going to do so, MiniYARNCluster constructor with enableAHS
param is not longer useful. We can remove it.
{code}
  public MiniYARNCluster(
      String testName, int numResourceManagers, int numNodeManagers,
      int numLocalDirs, int numLogDirs, boolean enableAHS) {
{code}

2. This case is covered already by the other tests. I think we are supposed to cover TIMELINE_SERVICE_ENABLED
= false and MAPREDUCE_JOB_EMIT_TIMELINE_DATA = true and false.
{code}
+    conf.setBoolean(YarnConfiguration.TIMELINE_SERVICE_ENABLED, true);
+    conf.setBoolean(MRJobConfig.MAPREDUCE_JOB_EMIT_TIMELINE_DATA, true);
{code}

> Currently the MiniMRYarnCluster does not consider the configuration value for enabling
timeline service before starting. The MiniYarnCluster should only start the timeline service
if it is configured to do so.
