Should AMRMClientAsync#CallbackHandler add method onAMCommand ?

I see that AllocateResponse has AMCommand which may request AM to resync or
shutdown, but I don't see AMRMClientAsync#CallbackHandler has any method to
handle that.   Should AMRMClientAsync#CallbackHandler add method
onAMCommand ?

I think are looking for Hadoop tutorial rather HDFS command guide. HDFS 
is just a file system which needs some conceptual knowledge to operate 
it. Check this

That’s a reference. I need something that says, “and this is how you interact with HDFS”. Everything I find talks a lot about how hdfs works but there is very little on how to move around in HDFS.

Re: Should AMRMClientAsync#CallbackHandler add method onAMCommand ?

Posted by Jeff Zhang <zj...@gmail.com>.
Thanks Hitesh, I only found onShutdownRequest is called
when ApplicationAttemptNotFoundException happens.
AllocateResponse#AMCommand is never checked.


AMRMClientAsyncImpl#HeartbeatThread

        try {

            response = client.allocate(progress);

          } catch (ApplicationAttemptNotFoundException e) {

            handler.onShutdownRequest();

            LOG.info("Shutdown requested. Stopping callback.");

            return;

          }
