------------------------------------------

[~ndimiduk]  Do you guys think it is just better to adjust the limit to account for 255 regions
instead?

> This happens because newer version of Phoenix sets salBuckets for sequence table to 256
creating 256 regions for salting by default.
> We can add the above config to Ambari's computed values – anything smaller than 10
RS's should use a value of $numRs * 5. Something like this. It could be a hassle for folks
who start small and add nodes; they'll need to split the table.
