Subject Rebuild HBASE Table to reduce Regions per RS
Date Tue, 14 Jan 2014 15:21:14 GMT
Does anyone have any experience rebuidling the HBASE table to reduce the
number of regions. I am currently dealing with a situation where the no. of
regions per RS have gone up quite significantly (500 per RS) and thereby
causing some performance issues. This is how I am thinking of bringing it

increase the hbase.hregion.max.filesize from 500 MB to 2 GB

And the rebuild the HBASE table. I am assuming if after table rebuild, I
should see the no. of regions come down to more than half. I would
basically like to stay within HBASE suggested no. of regions per RS which
is about 50-200.

Please suggest if someone has any experience doing it.
