Capacity Scheduler needs to re-read its configuration
-----------------------------------------------------
Key: HADOOP-4522
URL: https://issues.apache.org/jira/browse/HADOOP-4522
Project: Hadoop Core
Issue Type: New Feature
Reporter: Vivek Ratan
An external application (an Ops script, or some CLI-based tool) can change the
configuration of the Capacity Scheduler (change the capacities of various
queues, for example) by updating its config file. This application then needs
to tell the Capacity Scheduler that its config has changed, which causes the
Scheduler to re-read its configuration. It's possible that the Capacity
Scheduler may need to interact with external applications in other similar
ways.
