Allen Wittenauer commented on HDFS-6628:
----------------------------------------
Years ago, 'hadoop fs' and 'hadoop dfs' shell commands were deprecated (and
throw a warning to the user!) in favor of using the 'hdfs dfs' command. Doing
a simple grep revealed that the following documents still refer to 'hadoop fs'.
Instead, they should use be using 'hdfs dfs':
hadoop-hdfs-project aw$ grep -r 'hadoop fs' .
./hadoop-hdfs/src/main/java/overview.html:<p><tt>bin/hadoop fs -put input
input</tt></p>
./hadoop-hdfs/src/main/java/overview.html:bin/hadoop fs -get output output
./hadoop-hdfs/src/site/apt/ExtendedAttributes.apt.vm: The Hadoop shell has
support for interacting with extended attributes via <<<hadoop fs -getfattr>>>
and <<<hadoop fs -setfattr>>>. These commands are styled after the Linux
{{{http://www.bestbits.at/acl/man/man1/getfattr.txt}getfattr(1)}} and
{{{http://www.bestbits.at/acl/man/man1/setfattr.txt}setfattr(1)}} commands.
./hadoop-hdfs/src/site/apt/ExtendedAttributes.apt.vm: <<<hadoop fs -getfattr

./hadoop-hdfs/src/site/apt/ExtendedAttributes.apt.vm: <<<hadoop fs -setfattr

./hadoop-hdfs/src/site/apt/HdfsUserGuide.apt.vm: <<<bin/hadoop fsck>>>. For
