How to compare hdfs file with unix file?

I want to compare hdfs file with unix file.I know the one way using cat command we can compare files because of cat command also provided by Hadoop Distributed File System (HDFS).

Let's take one example :

# hdfs dfs -ls -R /demo

-rw-r--r--   3 root hdfs     129617 2014-10-17 12:22 /demo/abc.log

#ls /tmp
xyz.log

Here i want to compare abc.log to xyz.log. Any better approach??

You could probably use shell redirection + diff.

diff <(hdfs dfs -cat /demo/abc.log) <(cat /tmp/xyz.log)
