Jingcheng Du commented on HBASE-12669:
--------------------------------------
I'm thinking that we don't need this compaction scanner, we only pass a
ScanType.COMPACT_RETAIN_DELETES to the scanner, and dispatch the output cells
to store files or del files by the types (whether it's a delete type). Will
provide the patch later.
> Have compaction scanner save info about delete markers

> for the native mob compaction, we will need a scanner pass used the major
> compaction that records the delete markers in the mob-enabled columns. This
> would implement that core section.
