[jira] [Created] (HBASE-18448) Added support for refreshing HFiles through API and shell

Ajay Jadhav created HBASE-18448:
-----------------------------------

             Summary: Added support for refreshing HFiles through API and shell
                 Key: HBASE-18448
                 URL: https://issues.apache.org/jira/browse/HBASE-18448
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 1.3.1, 2.0.0
            Reporter: Ajay Jadhav
            Assignee: Ajay Jadhav
            Priority: Minor
             Fix For: 2.0.0, 1.4.0


In the case where multiple HBase clusters are sharing a common rootDir, even after flushing the data from
one cluster doesn't mean that other clusters (replicas) will automatically pick the new HFile. Through this patch,
we are exposing the refresh HFiles API which when issued from a replica will update the in-memory file handle list
with the newly added file.
This allows replicas to be consistent with the data written through the primary cluster.
