Subject [jira] Created: (HADOOP-3843) MiniMRCluster should have an idempotent shutdown
Date Mon, 28 Jul 2008 13:39:31 GMT
MiniMRCluster should have an idempotent shutdown

                 Key: HADOOP-3843
                 URL: https://issues.apache.org/jira/browse/HADOOP-3843
             Project: Hadoop Core
          Issue Type: Bug
            Reporter: Steve Loughran

It looks on a quick skim-through that the org.apache.hadoop.mapred.MiniMRCluster class has
nothing to stop a caller calling shutdown() more than once, with possible adverse consequences.
This will normally only show up if a test fails at precisely the wrong place.
