Joep Rottinghuis commented on YARN-4561:
----------------------------------------
All data that comes in late would be marked as suspicious. Only if accompanied
with non-suspicious data will we keep this. If there is no other normal of
final-value record we can discard this suspicious data.
> Compaction coprocessor enhancements: On/Off, whitelisting, blacklisting

> YARN-4062 deals with the flush and compaction related coprocessor basic
> functionality. We also need to ensure we can turn compaction on/off as a
> whole (in case of dealing with production issues) as well as provide a way to
> allow for blacklisting and whitelisting of processing compaction for certain
> records.
> For instance, we may want to compact only those records which belong to
> applications in that datacenter. This way we donot interfere with hbase
> replication causing coprocessors to process the same record in more than one
> dc at the same time.
> Also, we might want to not compact/process certain records, perhaps whose
> rowkey matches a certain criteria.
> Filing jira to track these enhancements
