> Project: HBase
> Issue Type: Improvement
> Affects Versions: 3.0.0, 1.3.6, 2.3.3
> Reporter: Sandeep Pal
> Assignee: Sandeep Pal
> Priority: Major
>
> ChainWalEntryFilter applies the filter on entry followed by filter on cells.
> If filter on cells remove all the cells from the entry, we should't
> replicate the entry.
> Here is the snippet for ChainWalEntryFilter filter. After filterCells we
> should check if there is any cells remaining in the entry.
> {code:java}
> @Override
> public Entry filter(Entry entry) {
> for (WALEntryFilter filter : filters) {
> if (entry == null) {
> return null;
> }
> entry = filter.filter(entry);
> }
> filterCells(entry);
> return entry;
> }{code}
