Jingcheng Du commented on HBASE-11861:
--------------------------------------
Hi Jon, [~jmhsieh], currently we don't have count information in the mob file,
I think it's better to have it in the metadata of each mob file. I'll open
another JIRA to implement that. Thanks.

> Key: HBASE-11861
> URL: https://issues.apache.org/jira/browse/HBASE-11861
> Project: HBase
> Issue Type: Sub-task
> Components: regionserver, Scanners
> Affects Versions: 2.0.0
> Reporter: Jonathan Hsieh
> Attachments: 141030-mob-compaction.pdf, mob compaction.pdf
>
>
> Currently, the first cut of mob will have external processes to age off old
> mob data (the ttl cleaner), and to compact away deleted or over written data
> (the sweep tool).
> From an operational point of view, having two external tools, especially one
> that relies on MapReduce is undesirable. In this issue we'll tackle
> integrating these into hbase without requiring external processes.
