--------------------------------------
Summary: Support explicit failover when automatic failover is
enabled
Key: YARN-1584
URL: https://issues.apache.org/jira/browse/YARN-1584
Project: Hadoop YARN
Issue Type: Sub-task
Components: resourcemanager
Affects Versions: 2.4.0
Reporter: Karthik Kambatla
Assignee: Karthik Kambatla
YARN-1029 adds automatic failover support. However, users can't explicitly ask
for a failover from one RM to the other without stopping the other RM. Stopping
the RM until the other RM takes over exposes the RM-ensemble to SPOF for the
duration.
It would be nice to allow explicit failover through yarn rmadmin -failover
command.
PS: HDFS supports -failover option.
