run an hdfs command using either hftp or webhdfs and it prints the following line to the console (system out)
Retrieving token from: https://NN_HOST:50470/getDelegationToken
Probably in the code where we get the delegation token. This should be removed as people using the dfs commands to get a handle to the content such as dfs -cat will now get an extra line that is not part of the actual content. This should either be only in the log or not logged at all.
