Sandeep Nemuri reassigned HDDS-2452:
------------------------------------
Assignee: Sandeep Nemuri
> Wrong condition for re-scheduling in ReportPublisher
> ----------------------------------------------------
>
> Key: HDDS-2452
> URL: https://issues.apache.org/jira/browse/HDDS-2452
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Attila Doroszlai
> Assignee: Sandeep Nemuri
> Priority: Trivial
> Labels: newbie
>
> It seems the condition for scheduling next run of {{ReportPublisher}} is
> wrong:
> {code:title=https://github.com/apache/hadoop-ozone/blob/master/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/report/ReportPublisher.java#L74-L76}
> if (!executor.isShutdown() ||
> !(context.getState() == DatanodeStates.SHUTDOWN)) {
> executor.schedule(this,
> {code}
> Given the condition above, the task may be scheduled again if the executor is
> shutdown, but the state machine is not set to shutdown (or vice versa). I
> think the condition should have an {{&&}}, not {{||}}. (Currently it is
> unlikely to happen, since [context state is set to shutdown before the report
> executor|https://github.com/apache/hadoop-ozone/blob/f928a0bdb4ea2e5195da39256c6dda9f1c855649/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/statemachine/DatanodeStateMachine.java#L392-L393].)
> [~nanda], can you please confirm if this is a typo or intentional?
