------------------------------------------
Sorry, this accidently went to the wrong project.
> Parquet scan fails when directory contains _SUCCESS or _logs

> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Steven Phillips

> _SUCCESS and _logs are often created from map reduce jobs, and typically
> ignored. This is commonly done using the OutputFilesFilter in hadoop.
> The new FooterGatherer class, which is used to read parquet footers in
> parallel, does not use this filter. So it attempts to read these as parquet
> files and fails.
> The fix is to use the DrillPathFilter, which extends OutputFilesFilter, in
> the FooterGather code.
