> 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}
