Sangjin Lee commented on YARN-4062:
-----------------------------------
Regarding getting access to YarnConfiguration, generically speaking there
should be a way for a co-processor to get a hold of HBaseConfiguration or
YarnConfiguration? I'm not too familiar with the HBase code, but I presume
there are ways...
I went over the latest patch, and it looks pretty good other than the
outstanding issue of the configuration and javadoc/whitespace/... violations. A
couple of additional minor issues:
- in TestHBaseStorageFlowRunCompaction.java, {{Connection conn}} in line 139
appears unused
- also in that file, {{ScanType scanType}} in line 199 is unused
> Add the flush and compaction functionality via coprocessors and scanners for
> flow run table

> As part of YARN-3901, coprocessor and scanner is being added for storing into
> the flow_run table. It also needs a flush & compaction processing in the
> coprocessor and perhaps a new scanner to deal with the data during flushing
> and compaction stages.
