Weiwei Yang commented on YARN-8693:
-----------------------------------
Hi [~Tao Yang]
Thanks for adding this. I have 2 comments regarding the patch.
1. In {{RMWebServices#signalToContainer}}, it throws a server-side exception
when something goes wrong in handling the request. Can we send a proper
response to client too? E.g
{code:java}
return Response.status(Status.INTERNAL_SERVER_ERROR).entity(e).build();
{code}
2. you please update the doc too?
Thanks

> Currently YARN has a RPC command which is "yarn container -signal <container
> ID [signal command]>" to signal
> OUTPUT_THREAD_DUMP/GRACEFUL_SHUTDOWN/FORCEFUL_SHUTDOWN commands to container.
> That is not enough and we need to add signalToContainer REST API for better
> management from cluster administrators or management system.
