Yi Liu commented on HDFS-9141: ------------------------------ +1 pending Jenkins, Thanks Uma. > Thread leak in Datanode#refreshVolumes > -------------------------------------- > > Key: HDFS-9141 > URL: https://issues.apache.org/jira/browse/HDFS-9141 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode > Affects Versions: 3.0.0, 2.7.1 > Reporter: Uma Maheswara Rao G > Assignee: Uma Maheswara Rao G > Attachments: HDFS-9141.00.patch > > > In refreshVolumes, we are creating executor service and submitting volume > addition tasks to it. > But we are not shutting down the service after the use. Even though we are > not holding instance level service, the initialized thread could be left out. > {code} > ExecutorService service = Executors.newFixedThreadPool( > changedVolumes.newLocations.size()); > {code} > So, simple fix for this would be to shutdown the service after its use. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
