Anton Gozhiy commented on DRILL-7520:
-------------------------------------
I made a fix by adding back some missing libraries. Here is the branch:
https://github.com/agozhiy/drill/tree/DRILL-7520. A one major disadvantage of
it is that the jdbc-all jar now contains MapR native client libs, and it is
bloated to 96919225B.
The better solution would be yo divide the jdbc-all to separate modules. There
is already a task for this: DRILL-6800.
