Description

Currently in IPCLoggerChannel#close, we have:

@Override
  public void close() {
    QuorumJournalManager.LOG.info("Closing", new Exception());
    // No more tasks may be submitted after this point.
    executor.shutdown();

Looks like this exception might be added just for debugging in HDFS-5074. We may want to either delete this line or replace it with some other log information.
