Description

In Hive, the Date type describes a particular year/month/day, in the form YYYY-­MM-­DD.
Hive has supported Date type in Parquet two years ago in Hive-1.2.0. (See https://issues.apache.org/jira/browse/HIVE-8119 and https://cwiki.apache.org/confluence/display/Hive/Parquet#Parquet-VersionsandLimitations.)

We should add support for Date type too.
