To bring on a split, try the following: 1. Set down the hbase.region.memcache.flush.size on your table. There is a bug that prevents you making this adjustment from the shell at the moment but for a workaround, see https://issues.apache.org/jira/browse/HBASE-903. 2. Then, wait till the optional flush runs (hbase.regionserver.optionalcacheflushinterval). Default is every 30 minutes. If you want to run permanently with the smaller split size, you should do as you posit, and lower the flush size -- hbase.hregion.memcache.flush.size -- in same proportion by which you lowered split size.
