How to make AM terminate if client crashes?

[John Lilley]

We have a YARN application that we want to automatically terminate if the YARN 
client disconnects or crashes.  Is it possible to configure the YarnClient-RM 
connection so that if the client terminates the RM automatically terminates the 
AM?  Or do we need to build our own logic (e.g. a direct client-AM connection) 
for that?
Thanks
