Subject [jira] Commented: (HADOOP-5913) Allow administrators to be able to start and stop queues
Date Tue, 16 Jun 2009 07:29:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719960#action_12719960
] 

Hemanth Yamijala commented on HADOOP-5913:
------------------------------------------

Rahul, the schedulingInfo member in Queue is an Object and not a string. Therefore, it cannot
be set to a default value like in JobQueueInfo. I verified that if the object is null, it
will not cause any damage elsewhere in code. This seems to be a valid assumption. For instance,
all calls to Queue.getSchedulingInfo (except in test cases) check for null before using the
object. Does this make sense for you ?
