    Description

      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.
