Erik Krogen commented on HDFS-14146:
------------------------------------
Nice job [~csun], this looks great! I have a few very minor style nits:
* The comment about blocking within {{internalQueueCall()}} is on the wrong
method ({{add()}} instead of {{put()}})
* For {{Server#requeueCall()}}, the {{throws}} should be on the same line as
the exceptions?
* You're missing a space before the curly brace on Server L2758
The test is clever!

> When we re-queue RPC call, the {{internalQueueCall}} will potentially throw
> exceptions (e.g., RPC backoff), which is then swallowed. This will cause the
> RPC to be silently discarded without response to the client, which is not
> good.
