Hello, I have 7-node hbase cluster (6 regionservers/hdfs nodes, 1 master), with one big table containing 500M+ entries.
It's a heavy-write light-read database. 1. Is it okay that the table has 1000+ regions for 6 regionservers only? 2. Is it okay that one regionserver is 10x as loaded as others? See http://michal.medvecky.net/rs.png . This is a constant state, not random. Row keys are random, not sequential. 3. Is it okay that index table has 1000+ regions as well? The problem is that I need to speed up writes and it does not seem that adding node helps. I'm using hbase 1.1.3 + phoenix 4.6.0 on hadoop 2.7.1 on Ubuntu 14.04. Thank you Michal
