Subject [jira] [Commented] (HDFS-9730) Storage ID update does not happen when there is a layout change
Date Mon, 01 Feb 2016 21:38:40 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15127085#comment-15127085

Chris Trezzo commented on HDFS-9730:

Thanks [~kihwal] for the catch. I am not quite sure I understand why the current unit tests
are actually passing. It seems as though both testUpgradeFrom22via26FixesStorageIDs and testUpgradeFrom22FixesStorageIDs
should be failing with the current trunk. Investigating this.

> This is because createStorageID() is no longer called when it goes through the layout
upgrade path.
