Subject Need Help: RegionTooBusyException: Above memstore limit
Date Mon, 02 Mar 2015 09:42:56 GMT

I'm constantly facing "RegionTooBusyException: Above memstore limit" errors
in one region server when writing data to HBase.

I checked the region server log, and I've seen a lot of warnings during the
data writes:

  WARN wal.fshlog couldn't find oldest seqNum for the region we're about to
flush, ...

Then HBase seem to flush the data and added it as a HStore file.

I also get a few warnings in client.ShortCircuitCache, says "could not load
... due to InvalidToken exceptions.

Anyone can give me hint what went wrong?

My HBase version is, I'm using HDP 2.1, but the release
is a little bit old.
