    Description

      Repro: run a scalding job that writes parquet files to a folder. no _metadata and _common_metadata file is created

      Impact: potential performance problem if parquet metadata is read from client side, which is the case for sparkSQL

      casue: the metatdata writing logic is in the mapreduce API but not the mapred API of parquet.
