I have an app that runs for a long time with no problems, but when I
signal it to shut down, I get errors like this:
java.io.IOException: Filesystem closed

at org.apache.hadoop.dfs.DFSClient.rename(DFSClient.java:502)

org.apache.hadoop.dfs.DistributedFileSystem.rename
(DistributedFileSystem.java:176)
The problems occur when I am trying to close open HDFS files. Any
ideas why I might be seeing this? I though it was because I was
abruptly shutting down without giving the streams a chance to get
closed, but after some refactoring, that's not the case.
