Subject [jira] [Commented] (MAPREDUCE-4271) Make TestCapacityScheduler more robust with non-Sun JDK
Date Wed, 07 Nov 2012 19:12:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13492603#comment-13492603
] 

Yu Gao commented on MAPREDUCE-4271:
-----------------------------------

The patch fixed the failure of testMultiTaskAssignmentInMultipleQueues and testQueueOrdering
with IBM JDK.

The NullPointException problem seems to be tracked by MAPREDUCE-4699
Testcase: testHighPriorityJobInitialization took 1.412 sec
	Caused an ERROR
null
java.lang.NullPointerException
	at org.apache.hadoop.mapred.JobHistory$JobInfo.logJobPriority(JobHistory.java:1969)
	at org.apache.hadoop.mapred.JobInProgress.setPriority(JobInProgress.java:895)
	at org.apache.hadoop.mapred.TestCapacityScheduler$FakeTaskTrackerManager.setPriority(TestCapacityScheduler.java:653)
	at org.apache.hadoop.mapred.TestCapacityScheduler.testHighPriorityJobInitialization(TestCapacityScheduler.java:2666)

> The capacity scheduler queue is initialized with a HashMap, the values of which are later
added to a list (a queue for assigning tasks). TestCapacityScheduler depends on the order
of the list hence not portable across JDKs.
