> This reminded me of something that [~bills] ran into and tried to get to the bottom of.
> My hunch was that somethign registered a shutdown hook which closed the filesystem object. I also remembered that FileSystem instances are cached.
> Bill pointed out that he thought this might still be a VFS related issue (despite having nothign to do with VFS). After I noticed a shutdown hook in our VFS usage, I think it's unsafe to be sharing FileSystem instances with VFS code that might also be used by Accumulo for important things like writing to files.
> We should get a unique FileSystem instance to provide to any VFS code. We can do this by:
> # Setting {{fs.hdfs.impl.disable.cache}} in the Hadoop Configuration we provide to {{FileSystem.get(Configuration)}}
> # Call {{FileSystem.newInstance(URI, Configuration)}}.
> Either seem to do what we want -- the latter possibly having more reliable semantics than just a configuration value.
