> DataWritableWriter strip spaces for CHAR type before writing. While when
> generating predicate, it does NOT do same striping which should cause data
> missing!
> In current version, it doesn't cause data missing since predicate is not well
> push down to parquet due to HIVE-17261.
> Please see ConvertAstTosearchArg.java, getTypes treats CHAR and STRING as
> same which will build a predicate with tail spaces.
