Adam Gilmore commented on DRILL-2879:
-------------------------------------
I've hit a similar issue to this (well, kind of the same). Basically, since
the Mongo driver was upgraded to 3.0, it now uses a different serialization
from BSON -> JSON. This means, where previously dates were serialized
(correctly) as { $date: "ISO8601" }, it now serializes as { $date:
timestamp_in_millis } and thus Drill blows up when querying Mongo with any
dates.
So really, this is quite a critical bug, as you can no longer query Mongo with
dates. I am testing the patch above to see if that resolves this issue, but I
think the points [~jnadeau] made re the oid are pretty valid.
