Junping Du updated MAPREDUCE-6621:
----------------------------------
Fix Version/s: 2.8.0
> Memory Leak in JobClient#submitJobInternal()
> --------------------------------------------
>
> Key: MAPREDUCE-6621
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6621
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Xuan Gong
> Assignee: Xuan Gong
> Fix For: 2.8.0, 2.7.3, 2.6.4, 3.0.0-alpha1
>
> Attachments: MAPREDUCE-6621.1.patch, MAPREDUCE-6621.2.patch
>
>
> In JobClient:
> {code}
> public RunningJob submitJobInternal(final JobConf conf)
> throws FileNotFoundException, IOException {
> try {
> conf.setBooleanIfUnset("mapred.mapper.new-api", false);
> conf.setBooleanIfUnset("mapred.reducer.new-api", false);
> Job job = clientUgi.doAs(new PrivilegedExceptionAction<Job> () {
> @Override
> public Job run() throws IOException, ClassNotFoundException,
> InterruptedException {
> Job job = Job.getInstance(conf);
> job.submit();
> return job;
> }
> });
> // update our Cluster instance with the one created by Job for submission
> // (we can't pass our Cluster instance to Job, since Job wraps the config
> // instance, and the two configs would then diverge)
> cluster = job.getCluster();
> return new NetworkedJob(job);
> } catch (InterruptedException ie) {
> throw new IOException("interrupted", ie);
> }
> }
> {code}
> We will replace the cluster object with the cluster object from Job, but the previous old cluster object would never be closed.
