------------------------------------------

             Summary: Delete operation not deleting sometimes  by Trigger augment method
                 Key: CASSANDRA-10599
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10599
             Project: Cassandra
          Issue Type: Bug
          Components: API, Core, Examples, Tools
         Environment: CentOS 6.6 Cassandra 2.2.2
            Reporter: Ashraful Islam


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 keySpace = properties.getProperty("keyspace");
		String columnFamily = properties.getProperty("table");
		if (!update.deletionInfo().isLive()) {
			CFMetaData cfMetaData = Schema.instance.getCFMetaData(keySpace, columnFamily);
			for (ColumnDefinition columnDefinition : cfMetaData.allColumns()) {
				System.out.println(CellNames.simpleSparse(columnDefinition.name));
				Mutation mutation = new Mutation(keySpace, key);
				mutation.delete(columnFamily, CellNames.simpleSparse(columnDefinition.name), System.currentTimeMillis());
			}
		}
	}
{code}

*This code is not deleting row with the same key that have been inserted with insert into
values command.*
*but if i insert the value by replacing*
{code}
mutation.delete(columnFamily, CellNames.simpleSparse(columnDefinition.name), System.currentTimeMillis());
{code}

*by* 

{code}
mutation.add(columnFamily, CellNames.simpleSparse(columnDefinition.name), ByteBufferUtil.bytes(35),
System.currentTimeMillis());
{code}

*in the above code, Then the value is deleted with the trigger*
