> Project: HBase
> Issue Type: Improvement

> Priority: Major

> HDFSBlockDistribution is used in different places like Balancer,
> DateTieredCompaction, CompactionTool etc. In Balancer area there is a config
> 'hbase.master.balancer.uselocality' using which we can skip this. But
> irrespective of this config, if we are on non HDFS FS, we should skip this.
> The block distribution issue many file status commands to underlying FS which
> wont be that cheap in a cloud FS. This jira aims at correcting all these
> places.
