Apache NiFi 2.6.0/2.7.2 ListSFTP Hostname not working when using Proxy Configuration Service. It works when an IP address is listed.
Example:
Hostname: cloudera.com
Port: 22
Proxy Configuration Service: StandardProxyConfigurationService (Proxy Type=HTTP)
When executed (run once), it gets the following error:
ListSFTP[id=a423ae96-019b-1000-c5c2-8e609a342bc5] Processing failed: org.apache.nifi.processors.standard.socket.ClientConnectException: SSH Connection failed [cloudera.com:22]
- Caused by: org.apache.sshd.common.SshException: DefaultConnectFuture[A@cloudera.com/<unresolved>:22]: Failed (UnknownHostException) to execute: cloudera.com
- Caused by: java.net.UnknownHostException: cloudera.com
When using the IP address of cloudera.com as 151.101.127.10 will work (disregard the proxy 403 error as it is not white listed)
ListSFTP[id=a423ae96-019b-1000-c5c2-8e609a342bc5] Processing failed: org.apache.nifi.processors.standard.socket.ClientAuthenticationException: SSH Authentication failed [151.101.127.10:22]
- Caused by: org.apache.sshd.common.SshException: [ssh-connection]: Failed (HttpProxyConnectException) to execute: http, none, proxy.*****.**/xxx.xx.xx.xxx:8080 => /151.101.127.10:22, status: 403 Forbidden
- Caused by: io.netty.handler.proxy.HttpProxyHandler$HttpProxyConnectException: http, none, proxy.*****.**/xxx.xx.xx.xxx:8080 => /151.101.127.10:22, status: 403 Forbidden
When the above is executed under NiFi 1.26.0 works fine with hostname or IP address when using the proxy.
Anyone have seen this issue?
Please advise.
