Sqoop >> mail # user >> com.sun.jersey.api.client.UniformInterfaceException returned a response status of 404 Not Found

com.sun.jersey.api.client.UniformInterfaceException returned a response status of 404 Not Found
Today I upgraded Sqoop 2 from 1.99.1 to 1.99.2.
Then, when I execute the command, "show job -a", I got the error messages
below.

sqoop:000> show job -a
Exception has occurred during processing command
Exception: com.sun.jersey.api.client.UniformInterfaceException Message: GET
http://MY_IP:12000/sqoop/v1/job/all returned a response status of 404 Not
Found

I found others may already meet this problem, but no one give explicit
answers to it.
http://mail-archives.apache.org/mod_mbox/sqoop-user/201307.mbox/%3C20130726162216.GE25269@localhost%3E

Next, I went to search the log files and saw the exceptions.

Does anyone know what happens to this situation and how to address it?

Thanks a lot!
