Summary: CellCounter improvements
Key: HBASE-15773
URL: https://issues.apache.org/jira/browse/HBASE-15773
Project: HBase
Issue Type: Improvement
Components: mapreduce
Reporter: Gary Helmling
Looking at the CellCounter map reduce, it seems like it can be improved in a
few areas:
* it does not currently support setting scan batching. This is important when
we're fetching all versions for columns. Actually, it would be nice to support
all of the scan configuration currently provided in TableInputFormat.
* generating job counters containing row keys and column qualifiers is
guaranteed to blow up on anything but the smallest table. This is not usable
and doesn't make any sense when the same counts are in the job output. The row
and qualifier specific counters should be dropped.
