Subject [jira] [Created] (HDFS-4676) TestHDFSFileSystemContract should set MiniDFSCluster variable to null to free up memory
Date Tue, 09 Apr 2013 01:29:14 GMT
Suresh Srinivas created HDFS-4676:
-------------------------------------

             Summary: TestHDFSFileSystemContract should set MiniDFSCluster variable to null
to free up memory
                 Key: HDFS-4676
                 URL: https://issues.apache.org/jira/browse/HDFS-4676
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
            Reporter: Suresh Srinivas
            Assignee: Suresh Srinivas
            Priority: Minor


TestHDFSFileSystemContract should reset the cluster member to null in order to  make garbage
collection quickly collect large chunk of memory associated with MiniDFSCluster. This avoids
OutOfMemory errors.

See https://issues.apache.org/jira/browse/HDFS-4434?focusedCommentId=13624246&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13624246
and the next jenkins tests where the OOM was fixed.
