Jinfeng Ni commented on DRILL-4384:
-----------------------------------
Applied the patches on the master branch. Run a query and check the query
profile. The query profile looks fine now.
+1.
On a side note, it would be good if we could add some sort of test, either in
unit test, or the pre-commit test suite, to ensure the query profile is
generated correctly. For now, seems such verification is missing, while the
query profile plays an important role to help analyze Drill's performance
issue. Without the automatic test, it's hard to track whether there is a
regression.

> Built drill from master branch (0a2518d7cf01a92a27a82e29edac5424bedf31d5) and
> started in embedded mode. Then,
> run a query and checked the query profile through WebUI. However,
> seems that the fragment profiles , operator profiles and visualized
> plan sections are all empty. Tried both Mac and CentOS and hit the same
> problem.
> After doing a binary search over recent commits, seems the patch of
> "DRILL-3581: Upgrade HPPC to 0.7.1" is the cause of broken query
> profiles [1]. The query profile on the commits before DRILL-3581
> looks fine.
