[jira] [Created] (HBASE-7303) Quit using reflection for the method DFSOutputStream#getNumCurrentReplicas(…)

Harsh J created HBASE-7303:
------------------------------

             Summary: Quit using reflection for the method DFSOutputStream#getNumCurrentReplicas(…)
                 Key: HBASE-7303
                 URL: https://issues.apache.org/jira/browse/HBASE-7303
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 0.96.0
            Reporter: Harsh J
            Assignee: Harsh J
            Priority: Minor


Given that we've raised our minimum version guarantee for HBase with 1.x carrying the 0.20-append code finally, and all subsequent releases (0.21*, 0.22, 0.23 and 2) have this method available in them, I don't see a reason to have the reflection based getNumCurrentReplicas invocation (via HDFS-826) anymore.

We could save ourselves quite a bit of perf. penalty by removing this check and simply calling the method directly, as its API has not changed across releases.
