[jira] [Commented] (HDFS-10506) OIV's ReverseXML processor cannot
reconstruct some snapshot details
[ 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).
