Sudheesh Katkam commented on DRILL-4046:
----------------------------------------
The only thing that is consistent about this regressions is that there are a
lot of fragments in this state (waiting to get the ISOChronology instance):

This has been fixed in the latest version of
[ISOChronology|https://github.com/JodaOrg/joda-time/commit/634066471f2941eddfcca3ed2a62c9d254cabccb].
What I don't understand is why DRILL-3242 (or patches around that) would make
this bug appear more frequently.

> (Time in milliseconds; 900 second timeout)
> + These regressions are not consistent i.e. on multiple runs, some runs do
> not vary from the baseline.
> + TPCH 18 did not regress without timing out (on runs until now).
