> The hadoop front-end script will print a deprecation warning and defer to the
> hdfs front-end script for certain commands, like fsck, dfs. If a wildcard
> appears as an argument then it can be inadvertently expanded by the shell to
> match a local filesystem path before being sent to the hdfs script, which can
> be very confusing to the end user.
> For example, the following two commands usually perform very different
> things, even though they should be equivalent:
> {code}
> hadoop fs -ls /tmp/\*
> hadoop dfs -ls /tmp/\*
> {code}
> The former lists everything in the default filesystem under /tmp, while the
> latter expands /tmp/\* into everything in the *local* filesystem under /tmp
> and passes those as arguments to try to list in the default filesystem.
