Subject [jira] [Created] (HDFS-11448) JN log segment syncing should support HA upgrade
Date Thu, 23 Feb 2017 19:56:44 GMT
Hanisha Koneru created HDFS-11448:
-------------------------------------

             Summary: JN log segment syncing should support HA upgrade
                 Key: HDFS-11448
                 URL: https://issues.apache.org/jira/browse/HDFS-11448
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


HDFS-4025 adds support for sychronizing past log segments to JNs that missed them. But, as
pointed out by [~jingzhao], if the segment download happens when an admin tries to rollback,
it might fail ([see comment|https://issues.apache.org/jira/browse/HDFS-4025?focusedCommentId=15850633&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15850633]).
