> The scenario is
> -> The split of a region takes a long time
> -> The deletion of the splitDir fails due to HDFS problems.
> -> Subsequent splits also fail after that.
> {code}
> private static void createSplitDir(final FileSystem fs, final Path splitdir)
>   throws IOException {
>     if (fs.exists(splitdir)) throw new IOException("Splitdir already exits? " + splitdir);
>     if (!fs.mkdirs(splitdir)) throw new IOException("Failed create of " + splitdir);
>   }
> {code}
> Correct me if am wrong? If it is an issue can we change the behaviour of throwing exception?
> Pls suggest.
