            Reporter: Kun Liu


Hi parquet-mr teams,

When I reading the parquet writer in [ParquetFileWriter]([https://github.com/apache/parquet-mr/blob/e06384455567c56d5906fc3a152ab00fd8dfdf33/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetFileWriter.java#L916),]  I find that there is no `column metadata` behind the each column chunk described in the [Parquet-Format] ([https://github.com/apache/parquet-format#file-format)] and [thrift definition]([https://github.com/apache/parquet-format/blob/54e53e5d7794d383529dd30746378f19a12afd58/src/main/thrift/parquet.thrift#L790)]
