Mit Desai commented on HDFS-6696: --------------------------------- [~andrew.wang], we were trying to upgrade 0.21.11 to 2.4.0 > Name node cannot start if the path of a file under construction contains > ".snapshot" > ------------------------------------------------------------------------------------ > > Key: HDFS-6696 > URL: https://issues.apache.org/jira/browse/HDFS-6696 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Kihwal Lee > Assignee: Andrew Wang > Priority: Blocker > > Using {{-renameReserved}} to rename ".snapshot" in a pre-hdfs-snapshot > feature fsimage during upgrade only works, if there is nothing under > construction under the renamed directory. I am not sure whether it takes > care of edits containing ".snapshot" properly. > The workaround is to identify these directories and rename, then do > {{saveNamespace}} before performing upgrade. -- This message was sent by Atlassian JIRA (v6.2#6252)
