Ming Ma updated YARN-1897:
--------------------------
Attachment: YARN-1897-2.patch
Xuan, thanks for the early patch. here is the updated version to expand
SignalContainerCommand and rename some methods.
1. SignalContainerResponse has a flag to indicate the request was submitted
successfully. If it fails, the application doesn't know why. Is that the
diagnosis string for? Previous patch just throws exception.
2. There is no unit test just for this patch. I tested it manually with related
changes in YarnCLI and RM to verify messages are being passed properly. When
other work items in RM and NM are added, unit tests will be added accordingly.
> Define SignalContainerRequest and SignalContainerResponse

> We need to define SignalContainerRequest and SignalContainerResponse first as
> they are needed by other sub tasks. SignalContainerRequest should use
> OS-independent commands and provide a way to application to specify "reason"
> for diagnosis. SignalContainerResponse might be empty.
