Hello, For access to data, because it’s considered more sensitive than the flow definition, both the user and the nifi node accessing the data must be granted permissions to view and modify data. Did you give the nodes permissions to view and modify data?
Also moving this from security@ to users@ mailing list, as this is more of a use-based question. The security@ mailing list should be used for sensitive topics such as potential vulnerabilities, etc. Thanks Mark Sent from my iPhone On Nov 22, 2022, at 4:58 AM, lemontree <715733...@qq.com> wrote: Hello we have secured Nifi cluster in 1.1.7 with 3 nodes.
