---------------------------------------------
Summary: Compiler probe MJ selection algorithm fallback
Key: HIVE-24793
URL: https://issues.apache.org/jira/browse/HIVE-24793
Project: Hive
Issue Type: Sub-task
Reporter: Panagiotis Garefalakis
Assignee: Panagiotis Garefalakis
As per discussion on #1286 current probe MJ selection algorithm:
* selects best MJ candidate (currently based on the distinct row ratio)
* does some further processing - which may bail out
Bailing out for the best candidate doesn't necessarily mean that we can not use
a less charming candidate. The extra compilation can be wrapped into to for
loop instead of selecting the best candidate the first part could be
implemented as a priority logic
