Zhihong Yu commented on HBASE-5737:
-----------------------------------
There is one more whitespace @ line 2986.
Please keep HashMap for now. For the case of two tables cited above, there is
time limit on the actual region movement per balance() call. Meaning the
balancing of the two tables may be completed in several iterations.
> Minor Improvements related to balancer.

> Currently in Am.getAssignmentByTable() we use a result map which is currenly
> a hashmap. It could be better if we have a treeMap. Even in
> MetaReader.fullScan we have the treeMap only so that we have the naming order
> maintained. I felt this change could be very useful in cases where we are
> extending the DefaultLoadBalancer.
