Subject AW: Able to connect to the same app master
Date Sat, 01 Aug 2015 16:00:38 GMT

your APPMaster could listen on a configurable Port for incomming requests an from here you
start to create your own mainenance module for this specific APP.

What is the client doing on the APP Master after submitting it into the Yarn-world? Is it
just about getting the progress of the APP or more use-case specific?

Is it possible to connect the app master of an application id if the current yarn client jvm
goes down.

To put this as a sequence of events, this is what I am looking for:

1. Launch an application, you get an app id in return
2. Machine at which client was running, gets rebooted. This will lead to jvm of yarn client
to get killed.
3. launch Yarn client in a mode, where i can specify the application id, so that i can reconnect
to the app master of that application id.

If there is any other way of achieving the same, by some other mechanism, please share over
