It’s a list of commands. That’s like giving me a big huge chest of automotive 
tools then telling me to go repair a car. I’m looking for something more along 
the lines of:

I am confused. The linked posted above tells you exactly that that how you 
interact with hdfs to do various tasks and features with examples.

What else are you looking for?

Re: Should AMRMClientAsync#CallbackHandler add method onAMCommand ?

2015-08-13 Thread Jeff Zhang 
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;

  }

Should AMRMClientAsync#CallbackHandler add method onAMCommand ?

2015-08-13 Thread Jeff Zhang 
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 ?
