Wei-Chiu Chuang commented on HDFS-9638:
---------------------------------------
I think we should file a separate JIRA to remove -mapredSslConf code and docs
entirely from hadoop 3.0.0, and make this JIRA entirely documentation
improvement. Because the end of hsftp support is an incompatible change in
hadoop 3.0.0
> Improve DistCp Help and documentation
> -------------------------------------

> Key: HDFS-9638
> URL: https://issues.apache.org/jira/browse/HDFS-9638
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: distcp
> Affects Versions: 3.0.0
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Minor
> Labels: supportability
>
> 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 "
