HDF Nifi is not responding and not use full CPU

New Contributor

Hi everyone


I have 3 HDF nodes and 4 HDP nodes, with hardware configuration 32CPU and RAM 32GB.

But i got an issue with HDF. The Nifi threads are always over 500% CPU but total system just uses about 20% of total CPU on all nodes.

So, Nifi UI is usually "not responding" and was rejected out of my cluster (see figure).

I also was set "Maximum Timer Driven Thread Count " to 64 (32, 80 both) and increase "Initial/Max memory allocation" to 4g/28g. But cannot resolve.

What's reason of this issue, How to configure Nifi up to maximize performance of CPU.


Please help

Thanks so much
