Tsz Wo (Nicholas), SZE commented on HDFS-2373:
----------------------------------------------
- There are quite a few System.out.println(..) in DelegationTokenFetcher. I
think all of them should change to LOG.debug(..).
- Should check LOG.isDebugEnabled() before calling LOG.debug(..).
- Need a patch for trunk.
> webhdfs and hftp print extra info to the console

> 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.
