-----------------------------------

             Summary: TestDFSClientExcludedNodes fails sporadically if excluded 
nodes cache expires too quickly
                 Key: HDFS-4633
                 URL: https://issues.apache.org/jira/browse/HDFS-4633
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 3.0.0
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


{{TestDFSClientExcludedNodes}} simulates failures of individual data nodes in 
the client's write pipeline and checks the client's ability to recover.  
HDFS-4246 added support for periodic "forgiveness" by caching the list of known 
bad data nodes with a periodic eviction.  The test uses a 1 second cache 
expiration.  This sometimes causes failed nodes to be forgiven too fast and 
violate the assumptions of the test.
