      Fix inconsistent value type ( String and Array ) of the "type" field for LeafQueueInfo in response of RM REST API
    • Flags:
      Important

      Description

      I see inconsistent value type ( String and Array ) of the "type" field for LeafQueueInfo in response of RM REST API - cluster/scheduler
      as per the spec it should be always String.

      here is the sample output ( removed non-relevant fields )

      {

          "schedulerInfo": {

        Thanks Varun Vasudev for explanation. I verified it in branch-2.7 that the test without main code change will failed with below failures:

        testClusterScheduler(org.apache.hadoop.yarn.server.resourcemanager.webapp.TestRMWebServicesCapacitySched)  Time elapsed: 0.463 sec  <<< FAILURE!
        org.junit.ComparisonFailure: "type" field is incorrect expected:<[capacitySchedulerLeafQueueInfo]> but was:<[["capacitySchedulerLeafQueueInfo"]]>
        	at org.junit.Assert.assertEquals(Assert.java:115)
        	at org.apache.hadoop.yarn.server.resourcemanager.webapp.TestRMWebServicesCapacitySched.verifySubQueue(TestRMWebServicesCapacitySched.java:378)
        	at org.apache.hadoop.yarn.server.resourcemanager.webapp.TestRMWebServicesCapacitySched.verifySubQueue(TestRMWebServicesCapacitySched.java:375)
        	at org.apache.hadoop.yarn.server.resourcemanager.webapp.TestRMWebServicesCapacitySched.verifyClusterScheduler(TestRMWebServicesCapacitySched.java:331)
        	at org.apache.hadoop.yarn.server.resourcemanager.webapp.TestRMWebServicesCapacitySched.testClusterScheduler(TestRMWebServicesCapacitySched.java:179)
        

        The test failure reported by Jenkins is not related and we already saw it many times (like in YARN-998).
        So +1. Patch LGTM. Will wait a while to commit in case someone else want to review it also.

        Thanks for the review Junping Du. I think there's definitely some JAXB implementation issue here. The test will fail on branch-2.6, branch-2.7 and passes in branch-2.8, branch-2 and trunk.

        The fix looks good to me. However, I think we should improve the test as it can pass without the fix.

        Thanks for the help Jayesh. I can reproduce it now. I'll try to find the root cause.

        prod env: linux 2.6.32-431.el6.x86_64 ( jdk 1.7.0_79)

        dev env ( where I can reproduce this issue) : mac os Yosemite (10.11.3 (15D21)) - jdk 1.7.0_79
        more info : this is bare hadoop code (hdp though - HDP-2.2.9.0-tag ) on which I am running the test cases to reproduce.

        Thanks for looking into this.. did you add test for type assessment in verifySubQueue() ?

        Jayesh - Sorry to annoy you about this - can you give me some details about your environment? I added a test for the type field but TestRMWebServicesCapacitySched passed for me.

        I tested on a Mac OS X - 10.11.2 with JDK 1.7.0_71 and on Ubuntu 14.04 with OpenJDK 1.7.0_79 and 1.8.0_72.

        Yes, This is reproducible, even with the test cases ( on HDP-2.2.9.0-tag )

        TestRMWebServicesCapacitySched.testClusterScheduler

        In this test case, "a1" subqueue has correct type, but "a2" subqueues always gets type as array.
        the test cases does not assert the type field in JSON response for sub-queues ( testClusterScheduler.verifySubQueue )

        Jayesh - is this reproducable on your end? I'm unable to produce this on my laptop. The "type" field is actually injected by JAXB and isn't a field we generate.
