Wellington Chevreuil updated HDFS-12117:
----------------------------------------
Attachment: HDFS-12117.006.patch
Thanks for the suggestions [~jojochuang]! Attaching a new patch with the Client
side tests added as suggested.
While implementing these, I noticed that *LocalFileSystem* currently has no
support for snapshot related methods. I'm not sure if that's intended to be
that way, or should we add support for this as well?
*TestHttpFSFileSystemLocalFileSystem* would fail when trying to run snapshot
related methods defined on *BaseTestHttpFSWith*, so for now, these tests would
only really run if *FileSystem* implementation is different from
*LocalFileSystem*.
For example, rename snapshot test:
{noformat}
private void testRenameSnapshot() throws Exception {
if (!this.isLocalFS()) {
Path snapshottablePath = new Path("/tmp/tmp-snap-test");
createSnapshotTestsPreconditions(snapshottablePath);
//Now get the FileSystem instance that's being tested
FileSystem fs = this.getHttpFSFileSystem();
fs.createSnapshot(snapshottablePath, "snap-to-rename");
fs.renameSnapshot(snapshottablePath, "snap-to-rename",
"snap-new-name");
Path snapshotsDir = new Path("/tmp/tmp-snap-test/.snapshot");
FileStatus[] snapshotItems = fs.listStatus(snapshotsDir);
assertTrue("Should have exactly one snapshot.",
snapshotItems.length == 1);
String resultingSnapName = snapshotItems[0].getPath().getName();
assertTrue("Snapshot name is not same as passed name.",
"snap-new-name".equals(resultingSnapName));
cleanSnapshotTests(snapshottablePath, resultingSnapName);
}
}

> Currently, HttpFS is lacking implementation for SNAPSHOT related methods from
> WebHDFS REST interface as defined by WebHDFS documentation [WebHDFS
> documentation|https://archive.cloudera.com/cdh5/cdh/5/hadoop/hadoop-project-dist/hadoop-hdfs/WebHDFS.html#Snapshot_Operations]
> I would like to work on this implementation, following the existing design
> approach already implemented by other WebHDFS methods on current HttpFS
> project, so I'll be proposing an initial patch soon for reviews.
