-----------------------------------------------
@Ted
{code}
boolean stillRunning = !threadPool.awaitTermination(
this.fileSplitTimeout, TimeUnit.MILLISECONDS);
{code}
We already do that. We wait for 30 secs. But the problem is the threads that
were spawned are still alive and later they issue the create command to NN.
Thus after we rollback and delete the splitdir it is again created by these
threads.
Correct me if am wrong Ted.

> 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.
