Yongjun Zhang commented on HDFS-12295:
--------------------------------------
About 2, User doesn't manually add the prefix at user command line parameters;
rather, it's the implementation of distcp, "hadoop fs -cp" etc that adds the
prefix (before calling getFileStatus and listStatus). So the path string
"inconsistency" may only appear inside HDFS core code, it may not be too bad.
what do you think [~daryn]? Thanks.

> Let NameNode to support prefix /.reserved/bypassExtAttr, so client can add
> thisprefix to a path before calling getFileStatus, e.g. /ab/c becomes
> /.reserved/bypassExtAttr/a/b/c. NN will parse the path at the very beginning,
> and bypass external attribute provider if the prefix is there.
