Subject [jira] [Commented] (HDFS-10506) OIV's ReverseXML processor cannot reconstruct some snapshot details
Date Thu, 13 Apr 2017 05:37:41 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15967162#comment-15967162

Akira Ajisaka commented on HDFS-10506:
--------------------------------------

Hi [~andrew.wang] and [~jojochuang], I'd like to backport this issue to 2.8.1. Possible incompatible
issue is that XML files generated by 2.8.1 XML processor cannot be parsed by 2.8.0 ReverseXML
processor, however, I'm thinking the situation is not likely happen. What do you think?

> OIV's ReverseXML processor cannot reconstruct some snapshot details.  Specifically, <fileDiff>
should contain a <snapshotCopy> and <blocks> field, but does not.  <dirDiff>
should contain a <snapshotCopy> field.  OIV also needs to be changed to emit these fields
into the XML (they are currently missing).
