Anu Engineer commented on HDFS-12098: ------------------------------------- [~cheersyang] Sorry to be so dense. I am not sure I understand what this means well. bq. However, in a real cluster environment. Scm constructor will not be called, so the port will not be bound. Looks like the main does call, SCM constructor {code} /** * Main entry point for starting StorageContainerManager. * * @param argv arguments * @throws IOException if startup fails due to I/O error */ public static void main(String[] argv) throws IOException { StringUtils.startupShutdownMessage(StorageContainerManager.class, argv, LOG); try { StorageContainerManager scm = new StorageContainerManager( new OzoneConfiguration()); scm.start(); scm.join(); } catch (Throwable t) { LOG.error("Failed to start the StorageContainerManager.", t); terminate(1, t); } } {code} > Ozone: Datanode is unable to register with scm if scm starts later > ------------------------------------------------------------------ > > Key: HDFS-12098 > URL: https://issues.apache.org/jira/browse/HDFS-12098 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: datanode, ozone, scm > Reporter: Weiwei Yang > Assignee: Weiwei Yang > Priority: Critical > Attachments: disabled-scm-test.patch, HDFS-12098-HDFS-7240.001.patch, > HDFS-12098-HDFS-7240.002.patch, Screen Shot 2017-07-11 at 4.58.08 PM.png, > thread_dump.log > > > Reproducing steps > # Start datanode > # Wait and see datanode state, it has connection issues, this is expected > # Start SCM, expecting datanode could connect to the scm and the state > machine could transit to RUNNING.
