MENG DING commented on YARN-4175:
---------------------------------
I am using the example application to test the container increase/decrease
function against a 4 node cluster. Will collect and report all problems when
the tests are completed.
Just a quick note in case someone also wants to do the test:
* The application master IPC server now listens on a fixed port 8686. If
multiple app masters are started on the same host with *-enable_ipc* option
specified, there will be port conflicts, but YARN should be able to start new
app attempts and try to launch app master on a different host.
* If there are invalid container resource change request (e.g., target resource
is smaller than original resource for increase), the AMRMClient will throw
exception (i.e. InvalidResourceRequestException) at the allocate call, and
current implementation of the distributed shell appmaster will exit, causing
the entire application to exit.
