Andrew Purtell created HBASE-6377:
-------------------------------------
Summary: HBASE-5533 metrics miss all operations submitted via
MultiAction
Key: HBASE-6377
URL: https://issues.apache.org/jira/browse/HBASE-6377
Project: HBase
Issue Type: Bug
Reporter: Andrew Purtell
A client application (LoadTestTool) calls put() on HTables. Internally to the
HBase client those puts are batched into MultiActions. The total number of put
operations shown in the RegionServer's put metrics histogram never increases
from 0 even though millions of such operations are made. Needless to say the
latency for those operations are not measured either. The value of HBASE-5533
metrics are suspect given the client will batch put and delete ops like this.
I had a fix in progress but HBASE-6284 messed it up. Before, MultiAction
processing in HRegionServer would distingush between puts and deletes and
dispatch them separately. It was easy to account for the time for them. Now
both puts and deletes are submitted in batch together as mutations.
