Ashvin Agrawal created HDFS-14889:
-------------------------------------
Summary: 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
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. This feature will be useful in hybrid scenarios when the local
cluster will host both kinds of blocks.
