[jira] [Commented] (YARN-1107) Restart secure RM with recovery enabled while oozie jobs are running causes the RM to fail during startup

Omkar Vinit Joshi commented on YARN-1107:
-----------------------------------------

The underlying problem is in below code. Here we are bypassing the rpc call if it is a local call. However we were updating the (localServiceAddress & localSecretManager) in ClientRMService.startService call. To fix this we are doing this updation call inside serviceInit. Now here we are making a reasonable assumption that rm port will be static (specified in config ..specifically port).

{code}
    private static ApplicationClientProtocol getRmClient(Token<?> token,
        Configuration conf) {
      InetSocketAddress addr = SecurityUtil.getTokenServiceAddr(token);
      if (localSecretManager != null) {
        // return null if it's our token
        if (localServiceAddress.getAddress().isAnyLocalAddress()) {
            if (NetUtils.isLocalAddress(addr.getAddress()) &&
                addr.getPort() == localServiceAddress.getPort()) {
              return null;
            }
        } else if (addr.equals(localServiceAddress)) {
          return null;
        }
      }
      final YarnRPC rpc = YarnRPC.create(conf);
      return (ApplicationClientProtocol)rpc.getProxy(ApplicationClientProtocol.class, addr, conf);        
    }
{code}
