Kihwal Lee created HDFS-6696:
--------------------------------
Summary: 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
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.
