> A RegionServer API has to be added which will return HDFSBlockDistribution
> for all the regions it hosts. RS already has this info cached and updated
> when flush/compaction happens. Master can query and get instead of hitting
> the namenode and caching. The larger the cluster becomes, the more costly it
> becomes to get this information and more stale the cached information becomes.
> This jira is only to add the API to regionserver.
