             Summary: Adding new methods in AbstractDelegationTokenSecretManager for restoring RMDelegationTokens on RMRestart
                 Key: HADOOP-9574
                 URL: https://issues.apache.org/jira/browse/HADOOP-9574
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Jian He


we're considering to add the following methods in AbstractDelegationTokenSecretManager for restoring RMDelegationTokens, these methods can also possibly be reused by hdfsDelegationTokenSecretManager, see YARN-638

  protected void storeNewMasterKey(DelegationKey key) throws IOException {
    return;
  }
  protected void removeStoredMasterKey(DelegationKey key) {
    return;
  }
  protected void storeNewToken(TokenIdent ident, long renewDate) {
    return;
  }
  protected void removeStoredToken(TokenIdent ident) throws IOException {

  }
  protected void updateStoredToken(TokenIdent ident, long renewDate) {
    return;
  }
