    Description

      Currently, Spark supported partial Hadoop compression codecs, but the Hadoop supported compression codecs and spark supported are not completely one-on-one due to Spark introduce two fake compression codecs none and uncompress.

      There are a lot of magic strings copy from Hadoop compression codecs. This issue lead to developers need to manually maintain its consistency. It is easy to make mistakes and reduce development efficiency.
