The way you can tell is in the documentation for a processor, by looking at the property description. If it says "Supports Expression Language: true" then you can reference variables. For example, with PutHDFS it looks like only the Directory property currently supports it:</P><P><A href="https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi.processors.hadoop.PutHDFS/index.html" target="_blank">https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi.processors.hadoop.PutHDFS/index.html</A></P> Fri, 09 Dec 2016 20:17:30 GMT bbende 2016-12-09T20:17:30Z https://community.cloudera.com/t5/Archives-of-Support-Questions/NiFi-PutHDFS-PutHiveQL-parameterization/m-p/145035#M48425 <P>I tried creating a custom.properties file with a variable for the below and defining that in nifi.properties file (nifi.variable.registry.properties=./conf/custom.properties).
