This is a basic NiFi->Accumulo integration. Running
mvn install will create your NAR, which can be added
to Apache NiFi. This is intended to be created with Apache NiFi 1.9+, though it may work with earlier versions.
The resulting NAR will be named 'nifi-accumulo-nar'
Note that some of this code was modeled after the HBase work.
Will add a ScanAccumulo feature along with delete and updates within PutRecord.
