Anyone have any pointers debugging why an odd HDFS close is failing?
Here is the exception I'm getting.

Its an open, write a few records and then a close. Usually it works.
My hadoop is TRUNK, perhaps a couple of hours old (r567876). Nothing in
dmesg. On this machine I only have 1024 file descriptors but I'd expect
to see complaint about file handles if this were the issue.
Thanks,
