title: Modify existing table split in hbase
body: <p>I have a HBase table created with 20 pre-created splits based on row key prefix. Now I want to increase the number of splits to 50 using the same method. Is there any way to do that in HBase? Dropping and re-creating the table with new splits is not an option as I have some hundreds of millions of rows in it and I want to retain it as it is and only increase the splits.</p>
