Secondary NN Heap Requirements.

avatar
New Contributor

Hi All,

I would like to know what is heap value that I need to set for SNN ?

I have a big cluster with ~600 nodes and ~150M blocks so I had set NN heap to be 150GB but what value should I keep for SNN ?

Currently its running with 8GB, I feel its low as it needs more MEM to perform checkpointing. 

Each hosts are running with 750GB of MEM.

Please suggest.
