> Key: YARN-5921
> URL: https://issues.apache.org/jira/browse/YARN-5921
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Varun Saxena
> Assignee: Varun Saxena
> Attachments: YARN-5921.01.patch, YARN-5921.02.patch
>
>
> Code in RMContextImpl is as under:
> {code:title=RMContextImpl.java|borderStyle=solid}
> void setHAServiceState(HAServiceState haServiceState) {
> synchronized (haServiceState) {
> this.haServiceState = haServiceState;
> }
> }
> public HAServiceState getHAServiceState() {
> synchronized (haServiceState) {
> return haServiceState;
> }
> }
> {code}
> As can be seen above, in setHAServiceState, we are synchronizing on the
> passed haServiceState instead of haServiceState in RMContextImpl which will
> not lead to desired effect. This does not seem to be intentional.
> We can use a RW lock or synchronize on some object here.
