org.apache.hadoop.hbase.client.HBaseAdmin.createTable()
Creates a new table. Synchronous operation. @param desc table descriptor for table @throws IllegalArgumentException if the table name is reserved @throws MasterNotRunningException if master is not running @throws TableExistsException if table already exists (If concurrentthreads, the table may have been created between test-for-existence and attempt-at-creation). @throws IOException if a remote or network exception occurs
