Chris Nauroth commented on HADOOP-13599:


{code}
  private static final AtomicBoolean closed = new AtomicBoolean(false);
{code}

Please make this a member variable, so multiple {{S3AFileSystem}} instances 
created within the same process can get closed independently.  I assume this is 
just a copy-paste error from {{warnedOfCoreThreadDeprecation}}, where 
{{static}} is appropriate.

{code}
  @Test
  public void testCloseReentrant() throws Throwable {
conf = new Configuration();
fs = S3ATestUtils.createTestFileSystem(conf);
fs.close();
fs.close();
  }
{code}

I suggest changing the name of this test method, because it doesn't really 
cover reentrancy.  It does cover idempotence though, so maybe 
{{testCloseIdempotent}}?
