> Its unclear to users which command to use to access the filesystem. Need some background and then we can fix accordingly. We have 3 choices:
> hadoop dfs -> says its deprecated and to use hdfs.  If I run hdfs usage it doesn't list any options like -ls in the usage, although there is an hdfs dfs command
> hdfs dfs -> not in the usage of hdfs. If we recommend it when running hadoop dfs it should atleast be in the usage.
> hadoop fs -> seems like one to use it appears generic for any filesystem.
> Any input on this what is the recommended way to do this?  Based on that we can fix up the other issues.
