Subject Re: distcp error.

Try taking a look at your NN logs to see why it had an internal server error.  I believe the
servlets are hardcoded to decode the path as UTF-8, but maybe the client used a different
encoding.

Hi, Tao. This problem is only with 2.0.1 or with the two versions?
Have you tried to use distcp from 1.0.3 to 1.0.3?

Hi, all
         I use distcp copying data from hadoop1.0.3 to hadoop 2.0.1.
         When the file path(or file name) contain Chinese character, an exception will throw.
Like below. I need some help about this.
         Thanks.
