Can't Connect to BigTable using Connection Factory - hadoop

Question

I am using a custom code to load HFiles directly into BigTable using the following API's
LoadIncrementalHFiles loader = new LoadIncrementalHFiles(conf);
loader.doBulkLoad(new Path(inputPath), admin, table, regionLocator);
while using ConnectionFactory I am using the following function in the statement
Connection connection = ConnectionFactory.createConnection(conf, null, null);
which always returns the parameter managed as false but I am getting the following error while running it.

Cloud Bigtable does not support LoadIncrementalHFiles. If you want to load data, your best bet is to use these instructions.
