-------------------------------------
Hi Guys,
Thanks for reporting the issue and the work here. [~daisuke.kobayashi], Per
Archana's description at
https://issues.apache.org/jira/browse/HDFS-9455?focusedCommentId=15082670&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15082670
The command line is "hadoop distcp webhdfs://IP:25003/test/testfile
webhdfs://IP:25003/myp" in a secured cluster with ssl enabled (both src and tgt
are the same cluster).
Would you please try it out in your env?
The "Invalid argument" msg is not very clear, when ssl is enabled, if we are
using webhdfs instead of swebhdfs, possibly we can improve the message to
indicate that.
Thanks.
