Description

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

    @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));
}

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

renewCount should not be used to verify this.
