Lars Hofhansl commented on PHOENIX-6090:
----------------------------------------

One more thing. This *only* happens with overwrites (updates of existing row 
keys).

So the script above can be changed to
{code:java}
> upsert into test values(rand()*100, rand()*100, rand(), rand(), rand());
> upsert into test select rand()*100, rand()*100, rand(), rand(), rand() from 
> test;
{code}
I.e. just generate 10.000 unique keys and hence more and more rows are being 
overwritten.

That shows the problem far quicker.

> 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

> This is Phoenix built from master and HBase built from branch-2.3. (Client 
> and server versions of HBase are matching)
