      Description

      Was inspecting a perf issue, where we needed the scanner metrics as counters for a MR job. Turns out that the HBase scan counters are no longer working in 1.0+. I think it got broken via HBASE-13030.

      These are the counters:

      	HBase Counters
      		BYTES_IN_REMOTE_RESULTS=0
      		BYTES_IN_RESULTS=280
      		MILLIS_BETWEEN_NEXTS=11
      		NOT_SERVING_REGION_EXCEPTION=0
      		NUM_SCANNER_RESTARTS=0
      		NUM_SCAN_RESULTS_STALE=0
      		REGIONS_SCANNED=1
      		REMOTE_RPC_CALLS=0
      		REMOTE_RPC_RETRIES=0
      		RPC_CALLS=3
      		RPC_RETRIES=0
