While de serializing the udfClass variable is becoming null because the class
is not present in MR classpath.
In user logs it is throwing the following exception
java.lang.ClassNotFoundException: com.samples.hive.udf.Grade
Continuing ...
So i have introduced one new variable to hold the udf class name like
udfClassName.
Now in the exception the class name will be displayed in the following way

Review request for hive and John Sichi.
Summary
---
while executing UDF if the implementation jar is not present in MR class path
it is throwing nullpointer exception instead of throwing nullpointer exception
throwing meaning full exception with the required details.
This addresses bug HIVE-2182.

John Sichi commented on HIVE-2182:

I agree with Chinna that in general we don't know whether the client-side class
availability matches the MR availability, so this extra check is useful.
However, can we improve the diagnostics? At a minimum, we want to know what
class is missing; if we can also say which .jar we saw it in on the
client-side, that would be great.
Code format nitpick: put opening curly brace on same line as if keyword.

Chinna Rao Lalam commented on HIVE-2182:
client side validation we can do while creating the temporary function this
scenario is already take care in the existing functionality. While creating
temporary function it is throwing exception if the UDF jar not in class
path(Hive Class path). If the requested jar in client class path and not in the
executed MR class path this issue will come example if the UDF jar maintained
in the HIVE/LIB and not executed add jar or not updated hive.aux.jars.path
this issue will come.

Hi He Yongqiang,
I feel this validation is not possible on client side because the client
side validation cannot
ensure the jar presence in task tracker classpath.

Instead of throwing the exception at runtime after starting the job, can we
also do some pre-procssing in the client side to catch this exception? Is that
easy to do?
