Wei-Chiu Chuang updated HDFS-9640:
----------------------------------
    Attachment: HDFS-9640.003.patch

Good catch! Thanks [~ajisakaa] for reviewing the patch,
I found three unused parameters in DistCpConstants.

I've also verified again there are no other unused parameters/variables/imports introduced by this patch.

> Per discussion in HDFS-9638,
> after HDFS-5570, hftp/hsftp are removed from Hadoop 3.0.0. But DistCp still makes reference to hsftp via parameter -mapredSslConf. This parameter would be useless after Hadoop 3.0.0;  therefore it should be removed, and then document the changes.
> This JIRA is intended to track the status of the code/docs change involving the removal of hsftp in DistCp.
