## Why CurrentCapacity exceeds MaximumCapacity?

New Contributor

I've configure queue default capacity to 20 dan maximum-capacity to 30. When I see with command "mapred queue -list", CurrentCapacity can exceeds MaximumCapacity (30) even its can exceeds 100% as seen in picture below.

Please explain me why this happen? Thank you.

Hi @nur majid,

In mapred queue -list output, default capacity and maximum capacity are with respect to Cluster' resources whereas current capacity is with respect to Queue's resources.

Example -

Assume cluster's resources - 10GB

Default Queue default capacity is 20% of cluster's resources which is 2GB

But default queue can go upto 30% of cluster's resources [maximum capacity] which is 3GB

Current capacity is 101% of Queue's capacity [Remember , queue's capacity is 2GB] , so it will come around 2.02GB which is less than 3GB[maximum capacity].
