+1 to that one, Jerry :). I think we're missing some context, Suli.
Also, I don't know of any code path in which an RPC would be partially
processed and then returned to the queue. Calls go from wire -> queue ->
handler, they can't move backwards. They either move forward or throw an
exception.

You may get a different mvcc number and get different results next time
around if there are concurrent writes.
Thanks,

Hi,
I am wondering, for read requests like Get/MultiGet/Scan, is the RPC
handling idempotent in HBase?
More specifically, if in the middle of RPC handling we stop the handling
threads, puts the RPC call back to the queue, and later another RPC Handler
picks up this call and starts all over again, will the result be the same
as if this call is being handled for the first time now? Or are their any
unexpected side effects?
Thanks!
Suli
