Right. As an example, I'm currently using ExecuteCommand to transfer data over an SSH pipe. I'm actually transferring data from a NiFi dataflow* to an HDFS cluster, using something like:
Command Path: bash Command Arguments: -c; ssh $host 'hadoop fs -appendToFile - /path/to/hdfs/file' For some reason (that I don't remember), I liked "bash -c" better than calling ssh straight in the "Command Path" property. I think maybe it had a better environment configuration that I needed. You might be able to just call ssh directly. * note, the nifi in question isn't directly on the hdfs network segment, so this was an easy/quick way to transfer data into hdfs from outside. ** ssh -X is not required, contrary to Oleg's comment. The -X option is for forwarding X Windows sessions, probably not what you need.
