Subject [jira] [Commented] (MAPREDUCE-3451) Port Fair Scheduler to MR2
Date Fri, 13 Jul 2012 17:53:36 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13413906#comment-13413906

Arun C Murthy commented on MAPREDUCE-3451:
------------------------------------------

bq. Digging more - looks like I don't see the fair-scheduler tests show up in hadoop-yarn-server-resourcemanager-3.0.0-SNAPSHOT-tests.jar.

Spoke too soon, I see the following:

{noformat}
$ jar -tvf ./hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/target/hadoop-yarn-server-resourcemanager-3.0.0-SNAPSHOT-tests.jar
| grep -i fair

   324 Fri Jul 13 10:37:20 PDT 2012 org/apache/hadoop/yarn/server/resourcemanager/scheduler/fair/TestFairScheduler$1.class

 25975 Fri Jul 13 10:37:20 PDT 2012 org/apache/hadoop/yarn/server/resourcemanager/scheduler/fair/TestFairScheduler.class
{noformat}

However, I don't see TestFSSchedulerApp, not sure why I don't see a compilation failure given
the wrong package declaration.

Patrick - any idea?

> The Fair Scheduler is in widespread use today in MR1 clusters, but not yet ported to
MR2. This is to track the porting of the Fair Scheduler to MR2 and will be updated to include
design considerations and progress.
