Memory Overcommit warning only for one host

[#1]

Hello,

We keep getting an overcommit warning for only one of our host. I understand we have a config issue but usually the warning applies on all concerned hosts.

we have exactly the same role configuration for 3 other hosts but no warning for them.

Any suggestions ?

Many thanks,

Regards,

Guillaume

You can not go by the only roles, in addition to that you need to check the memory consumed by each role by each node. Because it may not be balanced all ways...

To check that, as mentioned in the warning message, you have to go to

CM -> Hosts -> Node01 (or suitable) -> Resources -> Memory -> Get all the memory consumed by each node -> Manually SUM 
CM -> Hosts -> Node02 (or suitable) -> Resources -> Memory -> Get all the memory consumed by each node -> Manually SUM

Hello Saranvisa,

Thanks for your reply.

I guess it was not balanced untill now, since I've downsized yarn container memory to fit the host memory, all hosts have the exactly the same memory usage.
