Muhammad Gelbana commented on DRILL-4398:
-----------------------------------------
I face this error using v1.9 after I run very simple queries such as:
{code:sql}
SELECT A1.NAME
FROM
dfs.`/parquet_file_path` A1
LIMIT 10
{code}
Would someone kindly give an update on this ? Or may be a workaround ?
