-----------------------------------------
Summary: Capture locality data for debug
Key: IMPALA-7346
URL: https://issues.apache.org/jira/browse/IMPALA-7346
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Affects Versions: Impala 2.12.0
Reporter: Balazs Jeszenszky
With IMPALA-5872, it will be possible to capture and recreate query-specific
details when things break.
Currently there's no way to include data locality information in such test
cases. For example, if the original issue was reported from a 150 node cluster,
a reproduction on a 4 node test cluster is not guaranteed to be accurate.
Having the ability to 'pin' a plan (and just export that along with metadata)
is not a complete solution (it doesn't enable testing the planner itself).
A way to do this could be to to dump locality data to tblproperties.
