> Ability to check if a block has a replica on provided storage
> -------------------------------------------------------------
>
> Key: HDFS-14889
> URL: https://issues.apache.org/jira/browse/HDFS-14889
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Ashvin Agrawal
> Assignee: Ashvin Agrawal
> Priority: Major
>
> Provided storage (HDFS-9806) allows data on external storage systems to
> seamlessly appear as files on HDFS. However, in the implementation today,
> there is no easy way to distinguish a {{Block}} belonging to an external
> provided storage volume from a block belonging to the local cluster. This
> task simplifies this.
> {{isProvided}} block will be useful in hybrid scenarios when the local
> cluster will host both kinds of blocks. For e.g. policy for management of
> replica/cached-blocks will be different from that of regular blocks. As of
> this task {{isProvided}} is not invoked anywhere.
