Do we need JDK to be installed or JRE is enough to run Apache NIFI.

HI,

I want NIFI to be run with the minimum resource needed. my concern is whether I can run NIFI with JRE or JDK is also required. will I face any issues in future while scaling up?

I am using NIFI 1.15.3.

@shashikumar

NiFi only requires the the Java Runtime Environment (JRE). Latest versions of NiFi support both Java 8 or Java 11:
system_requirements

The JDK contains, in addition to the JRE, additional development tools like compilers, debuggers, etc. These may be useful to you depending on whether or not you intend to compile java code within your dataflow (not a requirement of any components like processors, controller services, reporting tasks, etc included with NiFi) or create your own custom NiFi components.
