Allen Wittenauer commented on HDFS-8685:
----------------------------------------
-1
* hdfs dfs is meant to be specifically for HDFS.
* Adding tools to hadoop fs (which is what one should be using when talking to
s3) is going to significantly slow it down for every single command.
* I don't think adding every single 3rd party file system to the default
command path is a good precedent.
* Users who want permanent support of a 3rd party file system should be using
shellprofile.d to enable such behavior.
> S3:Hadoop tools jars should be added in "dfs" class path.
