The HBase version is 0.98. After restarting the HBase, all the regions are shuffled across the cluster nodes and they are not evenly distributed. So I use the command balancer to rebalance the table. But the regions are not balanced by the table. Please see the following figure. Is there a way to make all regions are balanced by table?
I read an article about that but i could not find it now. Hbase assing regions by count to regions servers and as you see they are equal in each region server. but hbase does not have a table or load balancing feature when assigning regions so this leads heavy write/read tables in few regions and big and unused tables on other unused region servers.
if you google you can find a jira task in hbase project that they are tyring to fix this by adding table and load awareness to this process.
