@Prakash Thangavel, installing NiFi on Windows is pretty straight forward but there are a couple of limitations right now:
- There isn't an installer
- There isn't any Windows services integration for start/stop/restart
That said, it runs fine (and the Apache project does include Windows builds in its continuous integration). So, assuming you have a JDK/JRE installed, you can just download either the HDF or Apache NiFi .zip or .tar.gz, uncompress it to whatever desired location, and then run it by executing the batch script ./bin/run-nifi.bat.
I've seen a few issues pop up with installations on Windows, so there are some things to keep in mind:
- Make sure to use a 64-bit Java 1.7 or 1.8 JDK/JRE, especially if you're going to increase the heap size in ./conf/boostrap.conf.
- Recent versions of Windows sweep through C:\Program Files periodically and set all files to read-only, so installing NiFi in C:\Program Files doesn't work unless you change the location of ./conf/flow.xml.gz, ./conf/archive, ./logs, ./state, ./work, and all of the data repositories (./*_repository). Basically, install it somewhere besides C:\Program Files.
