RE: Is there any way to balance one table?
I mean region number is small.

Overall I have say 3000 region on 4 node, while this table only have 96 region. It won't be 24 for each region server, instead , will be something like 19/30/23/21 etc.

This means that I need to limit the slop to 0.02 etc? so that the balancer actually run on this table?

Best Regards,
Raymond Liu

What is the size of your table?

Hi

I do call balancer, while it seems it doesn't work. Might due to this table is small and overall region number difference is within threshold?

Hi Liu,

Why did not you simply called the balancer? If other tables are already
balanced, it should not touch them and will only balance the table which is not
balancer?

I choose to move region manually. Any other approaching?
0.94.1

Any cmd in shell? Or I need to change balance threshold to 0 an run
global balancer cmd in shell?

Best Regards,
Raymond Liu

What version of HBase are you using ?

0.94 has per-table load balancing.

Cheers

Hi

Is there any way to balance just one table? I found one of my
table is not balanced, while all the other table is balanced. So
I want to fix this table.
