HIVE-17593: DataWritableWriter strip spaces for CHAR type which causeâ¦
Parquet DataWritableWriter strip tailing spaces for HiveChar type, which
cause predicate push down failed to work due to ConvertAstToSearchArg
constructs predicate with tailing space. Actually, according to HiveChar
definition, it should contains padded value. ParquetOutputFormat can handle
tailing spaces through encoding.
