Andrew Wang commented on HDFS-5709: ----------------------------------- Test failure is the new test I added, use the binary diff to run it locally. > Improve upgrade with existing files and directories named ".snapshot" > --------------------------------------------------------------------- > > Key: HDFS-5709 > URL: https://issues.apache.org/jira/browse/HDFS-5709 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode > Affects Versions: 3.0.0, 2.2.0 > Reporter: Andrew Wang > Assignee: Andrew Wang > Labels: snapshots, upgrade > Attachments: hdfs-5709-1.patch > > > Right now in trunk, upgrade fails messily if the old fsimage or edits refer > to a directory named ".snapshot". We should at least print a better error > message (which I believe was the original intention in HDFS-4666), and [~atm] > proposed automatically renaming these files and directories. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
