Description

ENUM is used to annotate enum type in Thrift, Avro, and ProtoBuf, but it's not documented anywhere in parquet-format.

According to current (1.8-SNAPSHOT) code base, ENUM is only used to annotate BINARY. For data models which lack a native enum type, BINARY (ENUM) should be interpreted as a UTF-8 string.
