Lars Hofhansl commented on PHOENIX-6090:
----------------------------------------
Better test, just presplit the table. Shows that concurrent splits are not
necessary to cause this, just multiple regions (and thus multiple writers). The
test will either hang (causing the exception above in the RS) or fail pretty
quickly and a different count.
I'm going to stop looking into this for now.

> This was after I did some insert and a bunch of splits (but not in parallel).
> It's not, yet, clear under what circumstances that exactly happens. Just that
> after a while it happens.
> This is Phoenix built from master and HBase built from branch-2.3. (Client
> and server versions of HBase are matching)
