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.
