> For example,
> -mapredSslConf <arg>   Configuration for ssl config file, to use with
>                         hftps://
> But this ssl config file should be in the classpath, which is not clearly stated.
> http://hadoop.apache.org/docs/current/hadoop-distcp/DistCp.html
> "When using the hsftp protocol with a source, the security- related properties may be
specified in a config-file and passed to DistCp. <ssl_conf_file> needs to be in the
classpath. "
> It is also not clear from the context if this ssl_conf_file should be at the client issuing
the command. (I think the answer is yes)
> Also, in: http://hadoop.apache.org/docs/current/hadoop-distcp/DistCp.html
> "The following is an example of the contents of the contents of a SSL Configuration file:"
> there's an extra "of the contents of the contents "
