> I was trying to delete a row from one table when another table's row with the same primary key has been deleted
> {code:title=DeleteToDelete.java|borderStyle=solid}
> @Override
> public Collection<Mutation> augment(ByteBuffer key, ColumnFamily update) {

> 	String columnFamily = properties.getProperty("table");
> 	if (!update.deletionInfo().isLive()) {

> *This code is not deleting row with the same key that have been inserted with insert into values command.*
