Andrew Purtell commented on HBASE-10123:
----------------------------------------
bq. This will take a while so maybe we put this patch only in trunk and keep
0.98 as is since it would likely complicate any rolling upgrades from 0.96's
As you like. A release note indicating the port change and what needs to be
done in the site file to preserve the old settings in an existing deploy,
perhaps with a pointer to a section like this in the manual, would be
sufficient in my view.
> Change default ports; move them out of linux ephemeral port range

> Our defaults clash w/ the range linux assigns itself for creating come-and-go
> ephemeral ports; likely in our history we've clashed w/ a random, short-lived
> process. While easy to change the defaults, we should just ship w/ defaults
> that make sense. We could host ourselves up into the 7 or 8k range.
