> [~eclark] contributed a nice change on HBASE-14473 that scales calculation of
> locality balance cost to larger clusters. I'd like to bring this back to 0.98
> for folks running it on larger clusters. The changes require a partial
> rewrite of RegionLocationFinder hence a backport issue.
> The difference between this backport and RegionLocationFinder on later
> branches is we preserve the ability to change the expiration time of cache
> items with the configuration parameter
> "hbase.master.balancer.regionLocationCacheTime".
> The difference between RegionLocationFinder in 0.98 before and after this
> change is the expiration time of cache entries will be set according to when
> they are written into the cache instead of from when they are last accessed,
> which seems better to me.
