Subject One Mapper runs in ACID tables
Date Fri, 15 Jul 2016 01:24:24 GMT
Hi Team,

I have created ACID tables in Hive , while executing queries found a very
unusual behavior
Only one mapper runs if we have only delta files and in order to optimize
it we have to run major compactions to merge to base files

Want to confirm why we  have implemented it in this way and if any
correction in understanding is required please update
