> {{In Hive#copyFiles}} we have such code
> {code:java}
> if (src.isDirectory()) {
> try {
> files = srcFs.listStatus(src.getPath(), FileUtils.HIDDEN_FILES_PATH_FILTER);
> } catch (IOException e) {
> pool.shutdownNow();
> throw new HiveException(e);
> }
> }
> {code}
> If pool is null we will get NPE and actual cause will be lost.
> Initializing of pool
> {code:java}
> final ExecutorService pool = conf.getInt(ConfVars.HIVE_MOVE_FILES_THREAD_COUNT.varname, 25) > 0 ?
> Executors.newFixedThreadPool(conf.getInt(ConfVars.HIVE_MOVE_FILES_THREAD_COUNT.varname, 25),
> new ThreadFactoryBuilder().setDaemon(true).setNameFormat("Move-Thread-%d").build()) : null;
> {code}
> So in the case when the pool is not created we can get potential NPE and swallow an actual exception
