If you really want to re-implement it using Mutations on your own, you
can, but this is what the BatchDeleter is already doing for you.
You can use a (Batch)Scanner and a BatchWriter to read Key-Values,
create new Mutations from those Key-Values, and then submit them as
deletes with the BatchWriter. This is what the BatchDeleter is already
doing.
The 'new Authorizations("myauths")' was to remind you that, if you have
non-empty visibilities on the data you are reading, you need to provide
the correct authorizations to see that data. If you have empty
visibilities, you can just provide 'new Authorizations()'.

Hi,
Thanks for reply. This worked. But my design use Mutation. Can I do

Yes, use the Ranges that you provide to BatchDeleter#setRanges() to
control what data is deleted.
e.g. if you want to delete "colfam1" from "row5"
bd.setRanges(Collections.singleton(Range.exact(new Text("row5"))));
bd.fetchColumnFamily(new Text("colfam1"));

Wrong list, Ted? Looks like an HBase API.
I believe the easiest way to accomplish this is to use the BatchDeleter.
BatchDeleter bd = connector.createBatchDeleter("table", new
Authorizations("myauths"), 1, new BatchWriterConfig());
try {
bd.setRanges(Collections.singleton(new Range()));
bd.fetchColumnFamily(new Text("colfam"));
bd.delete();
} finally {
bd.close();
}

Hi Ted,
I didnt find this method. Can you share package, javadoc etc ?
Thanks

Take a look at the following method in Delete:
public Delete deleteFamily(byte [] family) {
