Subject [jira] Updated: (HDFS-521) Create new tests for pipeline
Date Tue, 27 Oct 2009 16:09:59 GMT

     [ https://issues.apache.org/jira/browse/HDFS-521?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Konstantin Boudnik updated HDFS-521:
------------------------------------

    Attachment: HDFS-521.patch

Fixing the race condition between two thread:
  - external thread tries to shutdown the cluster when a condition is met
  - main thread invokes @After method which checks cluster reference for null and then shuts
down datanodes and then the cluster itself. The cluster references might become null in between
of these two calls. Thus a separate check for null is in order.
