Creating Static Pools

To manage and prioritize workloads on clusters, use the static service pools to allocate dedicated resources for Impala for predictable resource availability. When static service pools are used, Cloudera Manager creates a cgroup in which Impala runs. This cgroup limits memory, CPU and Disk I/O according to the static partitioning policy.

Create static resource pools for the services running in your Cloudera cluster.
  1. In Cloudera Manager, navigate to Clusters > Static service pools.
  2. In the Configuration tab, allocate a portion of resource to each component.
    • HDFS always needs to have a minimum of 5-10% of the resources.

    • Generally, YARN and Impala split the rest of the resources.
      • For mostly batch workloads, you might allocate YARN 60%, Impala 30%, and HDFS 10%.

      • For mostly ad-hoc query workloads, you might allocate Impala 60%, YARN 30%, and HDFS 10%.
