org.apache.hadoop.hbase.client.HBaseAdmin.modifyTable()
Modify an existing table, more IRB friendly version. Asynchronous operation. This means that it may be a while before your schema change is updated across all of the table. @param tableName name of table. @param htd modified description of the table @throws IOException if a remote or network exception occurs
