Karthik Kambatla created YARN-1075:
--------------------------------------
Summary: serviceStart() semantic violation in certain services
Key: YARN-1075
URL: https://issues.apache.org/jira/browse/YARN-1075
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 2.1.0-beta
Reporter: Karthik Kambatla
Assignee: Karthik Kambatla
IIUC, the serviceStart() implementation of services should start local
threads/services first before calling super.serviceStart(). Certain services
have this reversed as below - leading to possibilities where the service would
be in state STARTED, but in reality might not have started yet.
{code}
void serviceStart() {
super.serviceStart()
// service sepecific logic and start operations
}
{code}
