Subject [jira] [Updated] (HDFS-12426) Ozone: BlockManager MBean unregister failure upon shutdown
Date Thu, 14 Sep 2017 19:01:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-12426?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lokesh Jain updated HDFS-12426:
-------------------------------
    Attachment: HDFS-12426-HDFS-7240.001.patch

The error occurs because BlockManager#close is called twice. The patch makes sure that MBean
unregister is only called once.
