Hi Gopal, 

I am attaching the following use cases output files: 

bad_udfs.out
bad_udfs_verbose.out
good_udfs.out
good_udfs_verbose.out

Usage: 

Normal mode: 
$ hive --service UDFLint -file /tmp/hive_udf-1.0.0.jar 
Verbose mode: 
hive --service UDFLint -jar yi/hive-json-serde-0.3.jar -v 
Without any options:
[root@sandbox test]#  hive --service UDFLint 
usage: udflint
 -h,--help                        print help message
    --hiveconf <property=value>   Use value for given property
    --jar <arg>                   Comma separated list of jars to validate
 -v,--verbose                     Verbose mode (Run the tool in debug
                                  mode)

Please let me know if you have questions. 

Thanks

> Several SerDe and UDF jars tend to shade in various parts of the dependencies including hadoop-common or guava without relocation.
> Implement a simple udflint tool which automates some part of the class path and shaded resources audit process required when upgrading a hive install from an old version to a new one.
