Subject Re: Need Help: RegionTooBusyException: Above memstore limit
Date Mon, 02 Mar 2015 14:59:00 GMT
What's the value for hbase.regionserver.global.memstore.size ?

Did RegionTooBusyException happen to many regions or only a few regions ?

How much heap did you give region servers ?

bq. HBase version is 0.98.0.2.1.2.0-402

Yeah, this is a bit old. Please consider upgrading.

Cheers
