Subject Compaction in hive
Date Tue, 06 Dec 2016 15:03:52 GMT
Dear Hive Gurus,

I am looking to some practical solution on how to implement *Compaction *in
Hive. Hiveserver2 version 1.1.0.

We have some external Hive tables on which we  need to implement

Merging the map files is one option which is turned down since it is very
CPU intensive.

Need your help in order to implement Compaction, how to implement, what are
the pros and cons.

Also, is it mandatory to have bucketing to implement compaction?

Request you to please help.

Thanks and Regards
Nishant Aggarwal, PMP
