Hudson commented on HDFS-4666:
------------------------------
Integrated in Hadoop-Hdfs-Snapshots-Branch-build #159 (See
[https://builds.apache.org/job/Hadoop-Hdfs-Snapshots-Branch-build/159/])
HDFS-4666. Define ".snapshot" as a reserved inode name so that users cannot
create a file/directory with ".snapshot" as the name. If ".snapshot" is used
in a previous version of HDFS, it must be renamed before upgrade; otherwise,
upgrade will fail. (Revision 1468238)
Result = FAILURE
