I think benchmark will do some help, since it can help to find out the
executing speed of I/O rated job and CPU rated job

This is a non-sense ; you have to tell us under which conditions you want
to find a bottleneck.

Regardless the workload, we mostly use OpenTSDB to check cpu times (iowait
/ user / sys / idle), disk usage (await, ios in progress...) and memory
(numa allocations, buffers, cache, dirty pages...)

Hi,
I wanted to understand, how should we find out the bottleneck of the
cluster?
Thanks
Krish
This is a vast topic.Can you tell what components are there in your data
pipe line and how data flows in to system and the way its processed.There
are several inbuilt tests like testDFSIO and terasort that you can run.

Basically we have 4 points to consider, CPU , Memory, IO and Network
So how to see which one is causing the bottleneck ?
What parameters we should consider etc ?
