NIFI-4160: SFTPTransfer connection timeout for opening channel.
----
> SFTPTransfer should specify connection timeout
> ----------------------------------------------

> Key: NIFI-4160
> URL: https://issues.apache.org/jira/browse/NIFI-4160
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.0.0
> Reporter: Koji Kawamura
> Assignee: Koji Kawamura
>
> For FTP/SFTP, we use com.jcraft.jsch library. When XXXSFTP processor make use of the library, there are two occasions to set connection timeout. One is connecting a session (Socket), and the other is opening a SFTP channel.
> Currently we set a connection timeout which can be specified via processor property for connecting a session, but not for opening an SFTP channel.
> Then the library uses default 10ms x 2000 retry to open the channel. With slow SFTP servers it's possible that opening channel takes longer than 10ms, which can cause following error:
> {code}
> java.io.IOException: Failed to obtain connection to remote host due to com.jcraft.jsch.JSchException: channel is not opened
> {code}
> We should specify connection timeout for opening channel as well.
