> _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.
