      Description

      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.
