Question about RPC call timeout

Hi all,

I have a very stress test on hbase by creating 1000 threads at the client
side, and each thread will call PUT function, and the client will throw out
some rpctimeout exception. It seems that the client will continue retrying
until the result is not NULL. Is that possible the rpc call already reach
the server rpc calllqueue, but still have timeout exception? If it is true,
does that mean the same rpc call will be executed twice?

Thanks a lot for your help.

Best,

Shu

Yes. For idempotent operations, the same rpc call can be executed twice.
