Subject [jira] [Created] (HDFS-11716) Revisit delete container API
Date Fri, 28 Apr 2017 01:54:04 GMT
Weiwei Yang created HDFS-11716:

             Summary: Revisit delete container API
                 Key: HDFS-11716
                 URL: https://issues.apache.org/jira/browse/HDFS-11716
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
            Reporter: Weiwei Yang
            Assignee: Weiwei Yang

Current delete container API seems can be possibly running into inconsistent state. SCM maintains
a mapping of container to nodes, datanode maintains the actual container's data. When deletes
a container, we need to make sure db is removed as well as the mapping in SCM also gets updated.
What if the datanode failed to remove stuff for a container, do we update the mapping? We
need to revisit the implementation and get these issues addressed. See more discussion [here|https://issues.apache.org/jira/browse/HDFS-11675?focusedCommentId=15987798&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15987798]
