> Replicaion scope set in WALObserver is getting reset in 
> Replication.scopeWALEdits(). 
> Because of this problem custom implementation of WALObserver can not be used 
> as a replication filter.
> Suppose WALObserver implementation has logic to filter all entries from 
> family f2
> {code}
> // Filter all family f2 rows
>   public static class ReplicationFilterWALCoprocessor extends BaseWALObserver 
> {
>     @Override
>     public boolean preWALWrite(ObserverContext<? extends 
> WALCoprocessorEnvironment> ctx,
>         HRegionInfo info, WALKey logKey, WALEdit logEdit) throws IOException {
>       ArrayList<Cell> cells = logEdit.getCells();
>       for (Cell cell : cells) {
>         byte[] fam = CellUtil.cloneFamily(cell);
>         if ("f2".equals(Bytes.toString(fam))) {
>           NavigableMap<byte[], Integer> scopes = logKey.getScopes();
>           if (scopes == null) {
>             logKey.setScopes(new TreeMap<byte[], 
> Integer>(Bytes.BYTES_COMPARATOR));
>           }
>           logKey.getScopes().put(fam, HConstants.REPLICATION_SCOPE_LOCAL);
>         }
>       }
>       return false;
>     }
>   }
> {code}
> This logic can not work as 
> {{org.apache.hadoop.hbase.replication.regionserver.Replication.scopeWALEdits()}}
>  recreates and populates scopes.
> *SOLUTION:*
> In Replication.scopeWALEdits(), create scopes map only if WALKey does not 
> have it.
> {code}
> NavigableMap<byte[], Integer> scopes = logKey.getScopes();
>     if (scopes == null) {
>       scopes = new TreeMap<byte[], Integer>(Bytes.BYTES_COMPARATOR);
>     }
