Add metrics to keep track of region-splits in RS
------------------------------------------------
Key: HBASE-5189
URL: https://issues.apache.org/jira/browse/HBASE-5189
Project: HBase
Issue Type: Improvement
Components: metrics, regionserver
Affects Versions: 0.90.5, 0.92.0
Reporter: Mubarak Seyed
Assignee: Mubarak Seyed
Priority: Minor
For write-heavy workload with region-size 1 GB, region-split is considerably
high. We do normally grep the NN log (grep "mkdir*.split" NN.log | sort | uniq
-c) to get the count.
I would like to have a counter incremented each time region-split execution
succeeds and this counter exposed via the metrics stuff in HBase.
- regionSplitSuccessCount
- regionSplitFailureCount (will help us to correlate the timestamp range in RS
logs across all RS)
