Lars Hofhansl commented on HBASE-8352:
--------------------------------------
This does not seem right:
{code}
+ // check if an older version of snapshot directory was present
+ Path oldSnapshotDir = new Path(mfs.getRootDir(), ".snapshot");
+ FileSystem fs = mfs.getFileSystem();
+ List<SnapshotDescription> ss = getCompletedSnapshots();
+ if (ss != null && !ss.isEmpty()) {
+ LOG.error("Snapshots from an earlier release were found under: " +
oldSnapshotDir);
+ LOG.error("Please rename the directory as " +
HConstants.SNAPSHOT_DIR_NAME);
+ }
{code}
If never used the old snapshot dir for anything and will just return the new
snapshots anyway.
> Rename '.snapshot' directory

> Testing HBase Snapshot on top of Hadoop's Snapshot branch
> (http://svn.apache.org/viewvc/hadoop/common/branches/HDFS-2802/), we found
> that both features used '.snapshot' directory to store metadata.
> HDFS (built from HDFS-2802 branch) doesn't allow paths with .snapshot as a
> component
> From discussion on [email protected], (see
> http://search-hadoop.com/m/kY6C3cXMs51), consensus was to rename '.snapshot'
> directory in HBase so that both features can co-exist smoothly.
