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.
-
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:
yarn.scheduler.capacity.root.yarn-system.capacity=10
-
Enable the
is_hbase_system_service_launch
property in
yarn-hbase.env
.
-
Restart YARN.
