Jean-Daniel Cryans commented on HBASE-8318:
-------------------------------------------
Generally, using ICV in MR jobs is a bad idea because of speculative execution
which is enabled by default, and even if it's disabled your tasks can just fail
and then they get restarted somewhere else and you never know how many times
you incremented some cells.
So, what's a valid use case for this jira?
> TableOutputFormat.TableRecordWriter should accept Increments
