-----------------------------------------------
@Ted
In trunk we sleep for a configured time and hence we handle
InterruptedException. But i think that is also not needed as in trunk once we
know file system is not available we do Runtime.halt(). If the file system is
available why do we need to sleep for some time and then retry.

> I am not sure if this bug was already raised in JIRA.
> In our test cluster we had a scenario where the RS had gone down and
> ServerShutDownHandler started with splitLog.
> But as the HDFS was down the check waitOnSafeMode throws IOException.
> {code}
> try {
> // If FS is in safe mode, just wait till out of it.
> FSUtils.waitOnSafeMode(conf,
> conf.getInt(HConstants.THREAD_WAKE_FREQUENCY, 1000));
> splitter.splitLog();
> } catch (OrphanHLogAfterSplitException e) {
> {code}
> We catch the exception
> {code}
> } catch (IOException e) {
> checkFileSystem();
> LOG.error("Failed splitting " + logDir.toString(), e);
> }
> {code}
> So the HLog split itself did not happen. We encontered like 4 regions that
> was recently splitted in the crashed RS was lost.
> Can we abort the Master in such scenarios? Pls suggest.
