Ted Yu updated HBASE-4669:
--------------------------

    Release Note: 
A new config parameter, hbase.master.enabletable.roundrobin, was introduced in this JIRA.
The default value is false and old behavior is kept.
When set true, regions of the table being enabled are assigned round-robin across the cluster.

> Under some scenarios, we use the function of disable/enable HTable. But currently, enable HTable uses the random-assignment. We hope all the regions show a better distribution, no matter how many regions and how many regionservers.
> So I suggest to add an option of using round-robin assignment on enable-table.
