----------------------------------------
Summary: Timeline v2 HBase Does Start After Upgrade Due to Missing
System Queue
Key: AMBARI-24483
URL: https://issues.apache.org/jira/browse/AMBARI-24483
Project: Ambari
Issue Type: Bug
Affects Versions: 2.7.0
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Fix For: 2.7.1
*During Upgrade*
# If cluster is big i.e >50GB and each machines has minimum 10GB resources
#* If *yarn-system* queue doesn't exist then we shall create a queue with *zero
capacity*.
#* All the necessary setting for queue such as *queue-priority*, *queue-acls*,
*disabling pre-emption* for this queue are set.
#* ats-hbase app queue name also set to *yarn-system*
#* But *do NOT* enable system service mode by default. Let upgrade happens in
embedded mode successfully.
#* Post upgrade, admin can change flag to enable system_service mode if
required by providing sufficient capacity to *yarn-system* queue. This step
*need to be documented.*
# If cluster is small
#* Continue upgrade in embedded mode without creating a yarn-system queue.
