[jira] [Created] (HDFS-7372) Active Replication Repair command / job

Hari Sekhon created HDFS-7372:
---------------------------------

             Summary: Active Replication Repair command / job
                 Key: HDFS-7372
                 URL: https://issues.apache.org/jira/browse/HDFS-7372
             Project: Hadoop HDFS
          Issue Type: New Feature
         Environment: HDP 2.1
            Reporter: Hari Sekhon


Please add an Active Replication Repair command / job as often under-replicated blocks take a long time to re-replicate as they're such low priority.

This will give operators the option to aggressively fully repair blocks during off-peak times rather than leaving a sub-optimal state.

This will also help in various testing scenarios around cross-DC DR, another area that needs to be addressed in HDFS.
