[jira] [Commented] (HDFS-14007) Incompatible layout when generating FSImage

    [ https://issues.apache.org/jira/browse/HDFS-14007?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16655833#comment-16655833 ] 

Íñigo Goiri commented on HDFS-14007:
------------------------------------

In HDFS-10706, [~ehiggs] mentioned the update of LAYOUT_VERSION from -63 to -64.
We should add a unit test that verifies that once the FSImage one changes.
