Jack Bearden commented on HBASE-20993:
--------------------------------------
Hi [~reidchan]! Thank you for providing guidance on this bug. I have been
working to reproduce it but do not yet see what you got. I am a bit stuck so I
have a few questions for you :)
# I was curious what client you used to get the errors there? Knowing this I
could setup a debugger and suspend around where the error is thrown. I have
been writing my own client but haven't been able to get that error yet
# Are there any existing tests I could also use as a framework to debug this?
I looked extensively and wasn't able to find any obvious use-cases. This would
be ideal if you knew a test that had a similar composition I can start from.
The RPC nature of this is a bit tricky... maybe mockito?
