NiFi: PutHDFS, PutHiveQL parameterization

[#1]

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). However, it invalidates the processor. Is there any other way to parameterize the following?

PutHDFS

Hadoop Configuration Resources

PutHiveQL

Database Connection URL

Hive Configuration Resources

Unfortunately not every property currently supports using the variable registry. 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:
