Sandy Ryza commented on HADOOP-9933:
------------------------------------
It looks like Guava doesn't allow its services to be restarted (ref:
http://stackoverflow.com/questions/8976367/restartable-service-using-guava).
Do we know any of the reasons they went with this design choice?
> Augment Service model to support starting stopped services
> ----------------------------------------------------------
>
> Key: HADOOP-9933
> URL: https://issues.apache.org/jira/browse/HADOOP-9933
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 2.1.0-beta
> Reporter: Karthik Kambatla
> Assignee: Karthik Kambatla
> Labels: service
>
> For ResourceManager-HA (YARN-149 and co), we would want to start/stop/start
> RM's active services as it transitions to Active/Standby/Active respectively.
> In the current service model, we can't start the services that are already
> stopped.
> Would be nice to augment this. To avoid accidental restart of stopped
> services, we can add another API: start(boolean restartIfStopped). Thoughts?
