--------------------------------------------------------
bq. didn't see any RegionTooBusyException...
[~eshcar] Yeah, we don't put them in the LOG... we just throw them to the
client. I see them in the MapReduce task logs, not in hbase regionserver logs.
Let me see if I can put up a metric or log message so we we can see when a
Region is struggling...
bq. and most flushes are when the memstore size is ~128MB, these are good news
I guess.....
Yes. This is good.
Let me fix the log line.
bq. Anyway, I would strongly suggest to compare performance to a setting where
G1GC is used and no MSLAB.
Hmm. This is another project, having hbase2 do G1GC by default. And MSLAB has
been enabled always. You folks think it should be off ([~anastas] you were
looking at this?) by default? It might make sense when G1GC is enabled but
proving this generally would be a bit of a project.
