Hello Rahul

 

Our Hive documentation [1] states currently "Hive in CDH does not support transactions (HIVE-5317)", so you can't use the Insert ,Update and Delete statements in Hive.

 

Based on the requirements you may want to consider using Kudu storage through Impala [2]

 

Please let me know if you have any more questions or concerns.
