> During normal operation the HRegion class reports a message related to memstore flushing in HRegion.class :
>       if (!canFlush) {
>         addAndGetGlobalMemstoreSize(-memstoreSize.get());
>       } else if (memstoreSize.get() != 0) {
>         LOG.error("Memstore size is " + memstoreSize.get());
>       }
> The log file is filled with lots of 
> Memstore size is: 190192
> Memstore size is: 442232
> Memstore size is: 190192

> These message are uninformative, clog up the logs and offers no root cause nor solution. Maybe the message needs to be more informative, changed to WARN or some further information provided.
