Ted Yu commented on HBASE-14309:
--------------------------------

Trying out on cluster, I got:
{code}
hbase(main):001:0> balancer

ERROR: undefined method `length' for nil:NilClass

Here is some help for this command:
{code}
Tried various ways according to google search which didn't work.
If I cannot figure out how to keep balancer command backward compatible, I plan 
to introduce a new command.

> Allow load balancer to operate when there is region in transition by adding 
> force flag

> This issue adds boolean parameter, force, to 'balancer' command so that admin 
> can force region balancing even when there is region in transition - assuming 
> RIT being transient.
> This enhancement was requested by some customer.
