Anu Engineer commented on HDFS-12098: ------------------------------------- [~cheersyang] Thanks for the analysis. I would love if MiniOzoneCluster is able to simulate issues in the real cluster. If we are able to reproduce issues in the real cluster using MiniOzoneCluster then it is a real win for us. Let me take a look at this, I am hoping the changes you are suggesting for SCM is not too complex to simulate this in MiniOzoneCluster. > 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.
