Josh Elser commented on HBASE-17852:
------------------------------------
bq. I do not see hot this can result in a distributed deadlock.
I think Andrew is just trying to warn about the kind of problem that can be
observed with Cross-RS RPCs. It's possible that some lock in one RS might
accidentally preclude some other RPC from completing. Or, if one RS executes
enough RPCs that saturate the handlers in another RS, we could soft-lock
(degrade and appear to be stuck). I don't think he's trying to tell you that he
believes there to be a concrete problem that exists in the implementation, just
giving context to why "Cross-RS RPCs" are oft considered smells and raise the
eyebrows they have raised.
Sorry if I'm putting words in your mouth (fingers), Andrew.
