Hive Import Action executes a hive load statement which loads data from HDFS directory/file location into a hive table.
Hive Import Action imports data from HDFS by executing provided Hive Load Statement.
Local file storage is not allowed because a pipeline can run on any machine. If LOCAL file storage option is provided,
pipeline deployment fails at publish time. Hive Import only accepts hive LOAD statements. If any other hive query is provided,
pipeline publish will fail.
If the Load command is executed successfully, all the files in the directory will be moved, not copied, to hive/warehouse directory. Hive import works with Hive 1.2.1.
