Konstantin Boudnik commented on MAPREDUCE-1882:
-----------------------------------------------
- The functionality seems to be common for MR and HDFS. Shall it be moved to
Common instead?
- This
{noformat}
+ jsch.setKnownHosts("/homes/" + user + "/.ssh/known_hosts");
{noformat}
is questionable.
- This one won't work if RSA identities are in use:
{noformat}
+ jsch.addIdentity("/homes/" + user + "/.ssh/id_dsa");
{noformat}
- Where Jsch will be coming from? Ivy dependency resolution needs to be added
as well.

> In herriot ( hadoop system test case dev) we often find that we are resorted
> to habit of ssh to remote node execute a shell command, and come out. It is
> wise to use Jsch instead of doing this through Shell.java ( hadoop code),
> since Jsch provides nice Java abstraction, the JIRA will only close after we
> import Jsch input hadoop build system and also fix all the existing test
> cases.
