The data sent over network does not seem to be compressed

We are using mapr c library to connect and write data to mapr FS.  The directory is configured as:

    $ hadoop mfs -ls /projects/silog/data
    drwxr-xr-x Z U U   - silog    silog    2 2015-12-10 11:54  268435456 /projects/silog/data/phase=PDT

So, it is compressed, unencrypted, and notaudited.  However, when checking with tcpdump on the client box (filtered by destination mfs host and port), it does not seem to be compressed before the data is sent over network:

![alt text][1]

as you can see clearly each character of the message.  Any clue why the message is not compressed?
