Subject [jira] [Created] (ACCUMULO-2228) Security randomwalk fails when namenode dies before bulk import
Date Mon, 20 Jan 2014 22:05:20 GMT
Bill Havanki created ACCUMULO-2228:

             Summary: Security randomwalk fails when namenode dies before bulk import
                 Key: ACCUMULO-2228
             Project: Accumulo
          Issue Type: Bug
          Components: test
    Affects Versions: 1.4.4
            Reporter: Bill Havanki

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

20 13:55:58,287 [retry.RetryInvocationHandler] WARN : Exception while invoking class org.apache.hado
op.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.create. Not retrying because the invoked
d is not idempotent, and unable to determine whether it was invoked Failed on local exception: Response is null.; Host

Caused by: Response is null.

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.
