Karan Mehta commented on PHOENIX-5101:
--------------------------------------
[~willshen] If you encountered the NPE, can you briefly describe the exact
environment in which this can be reproduced (HBase server and client version,
phoenix server and client version) and I can provide some insight after looking
into code.
The quick fix is obviously to bring back the null check again for the
scanMetricsMap, which is however not the correct way to do it as far as I
understand.
