--------------------------------
Summary: HA as a general YARN service to highlighted container by
application.
Key: YARN-4601
URL: https://issues.apache.org/jira/browse/YARN-4601
Project: Hadoop YARN
Issue Type: Sub-task
Components: applications
Reporter: Junping Du
Assignee: Junping Du
Priority: Critical
For LRS (long running services) on YARN, get rid of single point failure for
critical container failure may not be necessary. Some applications would like
to build its own HA architecture. However, it would be ideal to provide some
fundamental support to HA service in YARN, like: launching container marked
with active/standby, monitor/trigger out failed over, provide end point for
shring information between active/standby container, etc.
