[jira] [Created] (HBASE-17584) Expose ScanMetrics with ResultScanner rather than Scan

Duo Zhang created HBASE-17584:
---------------------------------

             Summary: Expose ScanMetrics with ResultScanner rather than Scan
                 Key: HBASE-17584
                 URL: https://issues.apache.org/jira/browse/HBASE-17584
             Project: HBase
          Issue Type: Sub-task
          Components: Client, mapreduce, scan
    Affects Versions: 2.0.0, 1.4.0
            Reporter: Duo Zhang
             Fix For: 2.0.0, 1.4.0


I think this have been discussed many times... It is a bad practice to directly modify the Scan object passed in when calling getScanner. The reason that we can not use a copy is we need to use the Scan object to expose scan metrics. So we need to find another way to expose the metrics.
