Jason Dere commented on HIVE-15955:
-----------------------------------
The point of this change (which should be added to the description) is to add a
feature to the formatted json explain which adds the Operator IDs to the json
output, and in the case of ReduceSinkOperators also saves the ID of the
operator following the RS (which is removed during plan generation).
- This outputs the operatorIDs, but the ReduceSinks do not have the IDs of
their following operators. This will need to be added in the step where the
link is removed in GenTezWork.
- This is for user-level explain .. I thought in the past the user-level
explain may have different information compared to normal explain, is there any
query metadata that might be missing in user explain that would be needed for
visual explain? cc [~cartershanklin]. Another possibility would be to have
another conf setting which enables display of the OperatorIDs (whether user
explain or not).
> make explain formatted to dump JSONObject when user level explain is on
