How to calculate number of total containers in cluster?

Does it depend on Memory? or VCores ? How can I get the exact number of containers which are available in my cluster.?

Hi Madhura,

 

The following link may be usefull for your question

https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.0.6.0/bk_installing_manually_book/content/rpm-chap...

 

For calculating  maximum number of containers allowed per node. The following formula can be used:

# of containers = min (2*CORES, 1.8*DISKS, (Total available RAM) / MIN_CONTAINER_SIZE)

Where MIN_CONTAINER_SIZE is the minimum container size (in RAM). This value is dependent on the amount of RAM available -- in smaller memory nodes, the minimum container size should also be smaller

 

Thanks
