Heng Chen commented on HBASE-16086:
-----------------------------------

What's the difference between "iterate over cells once" and "apply the "cell 
filtering" logic to these cells."

> TableCfWALEntryFilter and ScopeWALEntryFilter should not redundantly iterate 
> over cells.

> TableCfWALEntryFilter and ScopeWALEntryFilter both filter by iterating over 
> cells.  Since the filters are chained we do this work twice.  Instead iterate 
> over cells once and apply the "cell filtering" logic to these cells.
