Group ICVs waiting on row lock
------------------------------
Key: HBASE-2188
URL: https://issues.apache.org/jira/browse/HBASE-2188
Project: Hadoop HBase
Issue Type: Improvement
Reporter: Jean-Daniel Cryans
Fix For: 0.21.0
In the same spirit as group commit down in HLog, incrementColumnValue should be
grouping all requests waiting on the row lock into one in HRegion. This means
that 10 clients waiting on the lock should be all summed up and then applied
only once.
