> On HBASE-10018 we removed location prefetch in versions > 0.98. That issue
> enumerates some of the issues with location prefetch. It is already possible
> to disable location prefetch on a per table basis via
> HTable#setRegionCachePrefetch(TableName tableName, boolean enable) but we
> should have a site configuration option that disables prefetch globally
> without requiring application code take some special action like
> setRegionCachePrefetch.
