> Project: Apache Drill

> Reporter: Ramana Inukonda Nagaraj
> Assignee: Pritesh

> Files containing . and _ as the first characters are ignored by hive and
> others are these are typically logs and status files written out by tools
> like mapreduce. Drill should not read them when querying a directory
> containing a list of parquet files.
> Currently it fails with the error:
> message: "Failure while setting up Foreman. < AssertionError:[ Internal
> error: Error while applying rule DrillPushProjIntoScan, args
> [rel#78:ProjectRel.NONE.ANY([]).[](child=rel#15:Subset#1.ENUMERABLE.ANY([]).[],p_partkey=$1,p_type=$2),
