      Description

      mapreduce.security.token.DelegationTokenRenewal synchronizes on removeDelegationToken, but fails to synchronize on addToken, and renewing tokens in run().

      This inconsistency is exposed by frequent failures of TestDelegationTokenRenewal:

      Error Message
      
      renew wasn't called as many times as expected expected:<4> but was:<5>
