-------------------------------------------
[~iwasakims], thanks for the link there.
If that is the intended specification then it is not being enforced; but that
is a separate issue. Shall I close this JIRA then or re-purpose it?
> LocalFileSystem checksum file creation fails when source filename contains a

> In most FileSystems you can create a file with a colon character in it,
> including HDFS. If you try to use the LocalFileSystem implementation (which
> extends ChecksumFileSystem) to create a file with a colon character in it you
> get a URISyntaxException during the creation of the checksum file because of
> the use of {code}new Path(path, checksumFile){code} where checksumFile will
> be considered as a relative path during URI parsing due to starting with a
> "." and containing a ":" in the path.
> Running the following test inside TestLocalFileSystem causes the failure:
> {code}
> @Test
> public void testColonFilePath() throws Exception {
> FileSystem fs = fileSys;
> Path file = new Path(TEST_ROOT_DIR + Path.SEPARATOR + "fileWith:InIt");
> fs.delete(file, true);
> FSDataOutputStream out = fs.create(file);
> try {
> out.write("text1".getBytes());
> } finally {
> out.close();
> }
> }
> {code}
> With the following stack trace:
> {code}
> java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative
> path in absolute URI: .fileWith:InIt.crc
