Bharat Viswanadham updated HDDS-1476:
-------------------------------------
Component/s: Ozone Datanode
> Fix logIfNeeded logic in EndPointStateMachine
> ---------------------------------------------
>
> Key: HDDS-1476
> URL: https://issues.apache.org/jira/browse/HDDS-1476
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Bharat Viswanadham
> Priority: Major
> Labels: newbie
>
> {code:java}
> public void E(Exception ex) {
> LOG.trace("Incrementing the Missed count. Ex : {}", ex);
> this.incMissed();
> if (this.getMissedCount() % getLogWarnInterval(conf) ==
> 0) {
> LOG.error(
> "Unable to communicate to SCM server at {} for past {} seconds.",
> this.getAddress().getHostString() + ":" + this.getAddress().getPort(),
> TimeUnit.MILLISECONDS.toSeconds(
> this.getMissedCount() * getScmHeartbeatInterval(this.conf)), ex);
> }
> }{code}
> This method will be called when any exception occur in stateMachine to log an
> exception. But to not log aggresively we have this
> ozone.scm.heartbeat.log.warn.interval.count property to control logging.
>
> There is a small issue here, we don't log the exception first time when it
> occurred. So, we need to log for the first time and then increment the
> missingCount.
>
> Fix is to move the this.incMissed() to end of the method so that we log it
> for the first time exception occurred and after that every
> log.warn.interval.count exceptions happened.
