Subject Re: Need Help: RegionTooBusyException: Above memstore limit
Date Mon, 02 Mar 2015 15:04:23 GMT
Jo Jianshi,

Are you doing batch of puts? If so, what's the size of the batch and what's
the size of the puts? Are you trying to give a batch which at the end will
be bigger than the memstore size for a single RS? Can you try to reduce the
size of this batch?
