      Description

      Running Security randomwalk under HDFS HA, if the active namenode is killed:

      op.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.create. Not retrying because the invoked metho

      This arises from an attempt to write an rfile.The test should be resilient here (and for other file system operations) so that the test can continue once failover has completed.
