hi, all.
I got errors from hdfs.
2011-02-18 11:21:29[WARN ][DFSOutputStream.java]run()(519) : DataStreamer

I think this one is also not different error.

--> I've checked the file '/user/test/51/input/kids.txt ', but, there is
not strange ones. this file is healthy.
Does anybody know about this error?
How could I fix this one?
thanks.
