---------------------------------------
Summary: retain consistent splits /during/ (as opposed to across)
LLAP failures on top of HIVE-14589
Key: HIVE-14680
URL: https://issues.apache.org/jira/browse/HIVE-14680
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
see HIVE-14589.
Basic idea (spent about 7 minutes thinking about this based on RB comment ;))
is to return locations for all slots to HostAffinitySplitLocationProvider, the
missing slots being inactive locations (based solely on the last slot actually
present). For the splits mapped to these locations, fall back via different
hash functions, or some sort of probing.
