Enable System Service Mode On an Upgraded Cluster

On a cluster that is upgraded from HDP 2.6.5 to HDP 3.0+ and meets the capacity requirements for HBase to run in the system service mode, you must assign capacity to the yarn-system queue and enable the system service mode.

  1. Allocate required resources to the yarn-system queue for launching the ats-hbase service.
    The minimum amount of memory required for launching ats-hbase is 12 GB.
    To allocate resources, update the value of the yarn.scheduler.capacity.root.<queue_path>.capacity property in capacity-scheduler.xml. The following is an example:
  2. Enable the is_hbase_system_service_launch property in yarn-hbase.env.
  3. Restart YARN.
