Hi All, We have a HDP cluster behind a firewall and would like to use a NiFi flow from a different environment to write files (PutHDFS) to the HDP cluster. What are the approaches to achieve the same.
Probably you will need to use InvokeHTTP to issue a curl call to webhdfs.
There is also feature request open in regards to webhdfs processors:
In the mean time use the InvokeHTTP with curl, you might need to pass in an SSLContext into this InvokeHTTP to interact.
