---------------------------------
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.
