Allen Wittenauer commented on HDFS-7602:
----------------------------------------
Luckily, magic pre-dates Linux by a decade+ so we should be able to leverage
off of the BSDs or Illumos in order to avoid any license difficulties.
> HDFS file utility
> -----------------
>
> Key: HDFS-7602
> URL: https://issues.apache.org/jira/browse/HDFS-7602
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs-client, tools
> Affects Versions: 2.5.0
> Reporter: James Kinley
> Priority: Minor
>
> Provide a utility to determine HDFS file formats and compression types, akin
> to Linux's file utility.
> There is no easy way to do this today, short of downloading a file and
> running Linux's file utility on it for at least some intelligence. Although,
> Linux's magic file does not contain any information to identify the leading
> bytes of Hadoop's common file formats, for example: 'S', 'E', 'Q' for
> SequenceFiles, or 'P', 'A', 'R', '1' for Parquet.
