I tried to figure out this and found that for reading parquet footer this
class isn't used. For that purposes used `ParquetMetadata` from
parquet-hadoop-1.8.1-drill-r0.jar.
This class used for entire parquet directory with metadata cache file. When
it is absent an empty of this class is created.
I added some javadoc. Hope it will help.
