> {code:java}
> private static void createPath(HiveConf conf, Path path, String permission,
> boolean isLocal,
> boolean isCleanUp) throws IOException {
> FsPermission fsPermission = new FsPermission(permission);
> FileSystem fs;
> if (isLocal) {
> fs = FileSystem.getLocal(conf);
> } else {
> fs = path.getFileSystem(conf);
> }
> if (!fs.exists(path)) {
> fs.mkdirs(path, fsPermission);
> String dirType = isLocal ? "local" : "HDFS";
> LOG.info("Created " + dirType + " directory: " + path.toString());
> }
> if (isCleanUp) {
> fs.deleteOnExit(path);
> }
> }
> {code}
> The method {{fs.mkdirs(path, fsPermission)}} returns a boolean value
> indicating if the directory creation was successful or not. Hive ignores
> this return value and therefore could be acting on a directory that doesn't
> exist.
> Please capture the result, check it, and throw an Exception if it failed
