------------------------------------------------
Summary: Unable to see logs for Job end notification
Key: HADOOP-14522
URL: https://issues.apache.org/jira/browse/HADOOP-14522
Project: Hadoop Common
Issue Type: Bug
Reporter: Satish Subhashrao Saley
Hi, I have set {{mapreduce.job.end-notification.url}} and I am able to get the
notification correctly. But I am unable to see log lines from class
org.apache.hadoop.mapreduce.v2.app.MRAppMaster regarding job end notification.
When I was trying out different notification urls (before stabilizing my app),
I didn't have any way to look at the logs and wasted a lot of time figuring out
actual issue. It would be good if these logs are also included in syslog for
container.
[relevant
code|https://github.com/apache/hadoop/blob/branch-2.8/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app/src/main/java/org/apache/hadoop/mapreduce/v2/app/MRAppMaster.java#L641-L650]
{code}
notifyIsLastAMRetry(isLastAMRetry);
// Stop all services
// This will also send the final report to the ResourceManager
LOG.info("Calling stop for all the services"); <---- Able to see this.
MRAppMaster.this.stop();
if (isLastAMRetry) {
// Send job-end notification when it is safe to report termination to
// users and it is the last AM retry
if (getConfig().get(MRJobConfig.MR_JOB_END_NOTIFICATION_URL) != null) {
try {
LOG.info("Job end notification started for jobID : "
+ job.getReport().getJobId()); <--- unable to see this
JobEndNotifier notifier = new JobEndNotifier();
notifier.setConf(getConfig());
JobReport report = job.getReport();
{code}
Is it because we are shutting down all services including
JobHistoryEventHandler in {{MRAppMaster.this.stop();}} ?
