nats-messaging-for-nifi 
NATS Messaging processors for Apache NiFi
Version 0.5.2
ABOUT:
- Allows Apache NiFi to send/receive string based messages to/from NATS messaging topics.
- Based loosely on the Kafka processors that ship with NiFi.
- Tested on NiFi v0.4.1 and gnatsd Server v0.6.8
- Uses an embedded copy of https://github.com/mring33621/java_nats, which is a fork of https://github.com/tyagihas/java_nats, with some bug fixes.
- Java 7 or 8 compatible. Not sure about Java 6.
USAGE:
- Build the nifi-nats-bundle parent project with Maven. Make sure you clean all the target dirs first!
- Grab the .nar file from nifi-nats-nar/target and drop it into %NIFI_HOME%/lib.
- Restart NiFi.
- Now you can use the GetNats and PutNats processors.
