Already submitted to Jiri, but thought this should be brought to wider attention:
Although https://github.com/apache/nifi/pull/1361 was merged into master, it doesn't seem to function. It looks like expression language variables do not get evaluated if they are present in PORT or HOSTNAME. This causes the PutTCP to produce the following error: PutTCP[id=01601006-15cf-1651-ca50-f9597b0f303f] PutTCP [id=01601006-15cf-1651-ca50-f9597b0f303f] failed to process session due to java.lang.NumberFormatException: For input string: "": For input string: "" See Jiri Issue for example template.
