Subject [jira] [Commented] (YARN-4340) Add "list" API to reservation system
Date Thu, 17 Dec 2015 23:45:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15063107#comment-15063107
] 

Sean Po commented on YARN-4340:
-------------------------------

I made a comment about the test failures before, but to make it easier to find, I'll paste
it here again:

This patch addresses the remaining findbugs, checkstyle errors.
The following unit tests are failing and have associated Jira tickets:
        hadoop.yarn.server.resourcemanager.TestClientRMTokens 
                – YARN-4306
        hadoop.yarn.server.resourcemanager.TestAMAuthorization 
                – YARN-4318
        hadoop.yarn.client.TestGetGroups 
                – YARN-4351
The following unit tests are passing locally and flakiness may be related to YARN-4352:
        org.apache.hadoop.yarn.client.api.impl.TestYarnClient
                – testShouldNotRetryForeverForNonNetworkExceptions actually fails, but it
also fails locally on trunk
                – testAMMRToken
        org.apache.hadoop.yarn.client.api.impl.TestAMRMClient
        org.apache.hadoop.yarn.client.api.impl.TestNMClient
The following tests are passing locally:
        hadoop.mapreduce.v2.TestMRJobsWithProfiler

There are three new test failures above, but when I ran the tests locally, they all passed:
        hadoop.mapred.TestJobSysDirWithDFS
        hadoop.mapred.TestNetworkedJob
        hadoop.yarn.server.resourcemanager.scheduler.fifo.TestFifoScheduler

If you also look at the Hadoop QA comment from two days ago, where the code only changed with
regards to style, there were very few test failures, which indicates that some of the above
tests are flaky:

JDK v1.8.0_66 Failed junit tests	
        hadoop.yarn.server.resourcemanager.TestAMAuthorization
 	hadoop.yarn.server.resourcemanager.scheduler.fifo.TestFifoScheduler
 	hadoop.yarn.server.resourcemanager.TestClientRMTokens

> This JIRA tracks changes to the APIs of the reservation system, and enables 
> querying the reservation system on which reservation exists by "time-range, reservation-id".
> YARN-4420 has a dependency on this.
