Alexander Zarei commented on DRILL-2767:
----------------------------------------
Update: I ran to same same issue again. It seems like the metastore is not the
problem. It seems like the time proximity between the queries could be the
cause of the problem as after about 15 minutes I could run the query again.
I will upload the logs shortly here.
