异常 : IllegalArgumentException: You tried to write a BigInt type when you are using a ValueWriter of type NullableIntWriterImpl.

==>
Corrupted JSON records in MongoDB can cause this.
You can handle this using exec.enable_union_type
option.
Fire query:
ALTER SYSTEM SET `exec.enable_union_type` = true;
Or go to http://localhost:8047/options (assuming drill is running on local machine replace with IP if not)
And change exec.enable_union_type
to true.
