Patch to add warnings on skew not big enough to warrant killing the RS.

 Add a clock skew warning threshold

 Key: HBASE-5770
 URL: https://issues.apache.org/jira/browse/HBASE-5770
 Project: HBase
  Issue Type: Improvement
  Components: master, regionserver
Reporter: Ian Varley
Priority: Minor
 Attachments: HBASE_5770_v1.patch

   Original Estimate: 1h
  Remaining Estimate: 1h

 There's currently an exception thrown by the master when a region server 
 attempts to start up with clock skew greater than some configured amount 
 (defaulting to 30 seconds). However, it'd be nice to get some warnings logged 
 at a value that isn't severe enough to warrant killing the RS, but still 
 represents significant skew that could affect correctness. Will attach a 
 simple patch to add this as a setting.

Attachment: ClientScanner_HBASE_5717-v3.patch

Added additional test cases for running off the end of the available results 
without closing the scanner, and also doing so with closing the scanner (so, 
all 3 permutations are covered).

 Scanner metrics are only reported if you get to the end of a scanner
 

 Key: HBASE-5717
 URL: https://issues.apache.org/jira/browse/HBASE-5717
 Project: HBase
  Issue Type: Bug
  Components: client, metrics
Reporter: Ian Varley
Priority: Minor
 Attachments: ClientScanner_HBASE_5717-v2.patch, 
 ClientScanner_HBASE_5717-v3.patch, ClientScanner_HBASE_5717.patch

   Original Estimate: 4h
  Remaining Estimate: 4h

 When you turn on Scanner Metrics, the metrics are currently only made 
 available if you run over all records available in the scanner. If you stop 
 iterating before the end, the values are never flushed into the metrics 
 object (in the Scan attribute).
 Will supply a patch with fix and test.
