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

             Summary: o.a.h.fs.TestDelegationTokenRenewer is failing intermittently
                 Key: HADOOP-9113
                 URL: https://issues.apache.org/jira/browse/HADOOP-9113
             Project: Hadoop Common
          Issue Type: Bug
          Components: security, test
    Affects Versions: 2.0.2-alpha
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla
             Fix For: 2.0.3-alpha


In the following code snippets, the test tries to check the renewCount for the token to verify
if the FileSystem has been de-queued.

{code}
    @Override
    public long renew(Configuration conf) {
      if (renewCount == MAX_RENEWALS) {
        Thread.currentThread().interrupt();
      } else {
        renewCount++;
      }
      return renewCount;
    }

testAddRemoveRenewAction() {
  // some test code
  assertTrue("Token not removed", (tfs.testToken.renewCount < MAX_RENEWALS));
}
{code}

On slower machines, the renewCount can actually reach MAX_RENEWALS resulting in a test failure.

renewCount should not be used to verify this.
