      In sql,

      1.Query the existing  udf(say myFunc1)

      2. create and select the udf registered with incorrect path (say myFunc2)

      3.Now again query the existing udf  in the same session - Wil throw exception stating that couldn't read resource of myFunc2's path

      4.Even  the basic operations like insert and select will fail giving the same error

      Result:
