Hello,
I'm having isssue running Hive jobs after updating from Hive 0.5 to Hive
0.7 (from CDHb4 to CDHu1).
No matter what query I'm running Hive is always using one mapper.
I have tried different queries with various sizes of input and ones with
many reducers or no reducers.
For version 0.5 everything worked correctly.
I'm attaching my hive-site.xml: https://gist.github.com/1111531
I have tested also jobs with Pig, and those jobs use multiple mappers -
so I guess this is a Hive issue.
Thank you for all your help.
