Subject Re: Adding new node in cluster (Load balancer)
Date Fri, 09 Dec 2016 18:34:45 GMT
Unfortunately the difference in available space per node won't be
considered by the HBase balancer, but it shouldn't matter since you are
adding more space.  Worst case scenario is that you will start filling up
the other disks first before the one with the 6TB.

cheers,
esteban.
