> When master starts up and tries to do splitlog, in case of any error we try to do that infinitely in a loop until it succeeds.
> But now if we get a shutdown call, inside SplitLogManager
> {code}
> if (stopper.isStopped()) {
> LOG.warn("Stopped while waiting for log splits to be completed");
> return;
> }
> {code}
> Here we know that the master has stopped. As the task may not be completed now
> {code}
> if (batch.done != batch.installed) {
> batch.isDead = true;
> tot_mgr_log_split_batch_err.incrementAndGet();
> LOG.warn("error while splitting logs in " + logDirs +
> " installed = " + batch.installed + " but only " + batch.done + " done");
> throw new IOException("error or interrupt while splitting logs in "
> + logDirs + " Task = " + batch);
> }
> {code}
> we throw an exception. In MasterFileSystem.splitLogAfterStartup() we don't check if the master is stopped and we try continously.
