Does anyone have advice on configuring the thread count in Yarn? What is the implication of a high count for the following configurations (memory, CPU, etc.):
Any advice would be appreciated.
Why are you looking at changing these values? Do you have a really large node or are you looking at a large cluster?
You need to provide more details before we can say if you should change and to what you should change them.
Wilfred, I'm more interesting in understanding these parameters. I can't find good documentation about the thread-count parameters. What effect would changing the thread-count have on memory or CPU of a node?
