Description
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.
