> I just verified that the issue is not observed on Drill 0.6, 0.7-r2. It is observed on Drill 0.7-R3 & Drill 0.8 (Have logs from each run for reference)
> Also, on Drill 0.7-R3 (& Drill 0.8), the issue is not observed when i query any regular json/text/parquet files. This is seen only when I query any MapR-DB table /view. After which I cannot query any file on any schema. On restarting drill-bits, I can begin querying other schemas.
