Dev Lakhani commented on HBASE-13452:
-------------------------------------
I don't see that anywhere before or after the "Memstore size" error or indeed
anywhere in our logs for master and regions. We have INFO level logging though.
Real examples of memstore sizes are:
Memstore size is 4390632
Memstore size is 558744
Memstore size is 4390632
Memstore size is 558744
> HRegion warning about memstore size miscalculation is not actionable

> Reporter: Dev Lakhani
> Priority: Blocker
> Fix For: 2.0.0, 1.1.0, 1.0.2

>
> 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.
