Hi, 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 down:
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. Thanks Upen
