Why Is the Resource Pool Memory Displayed in the MRS Cluster Smaller Than the Actual Cluster Memory?

Updated on 2022-09-14 GMT+08:00

In an MRS cluster, MRS allocates 50% of the cluster memory to Yarn by default. You manage Yarn nodes logically by resource pool. Therefore, the total memory of the resource pool displayed in the cluster is only 50% of the total memory of the cluster.
