Description

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; }

Also move addPersistedDelegationToken in hdfs.DelegationTokenSecretManager, to AbstractDelegationTokenSecretManager
