UDF classpath issue

[#1]

I have a UDF which has a dependency of commons-lang3-3.4, the version which is part of hive-exec is different, as a result, am getting NoSuchMethodError, even after using HADOOP_USER_CLASSPATH_FIRST is not allowing me to set my own jar as preference, 

[#2]

I get the following error 

Caused by: java.lang.NoSuchMethodError: org.apache.commons.lang3.StringUtils.isNoneBlank([Ljava/lang/CharSequence;)Z
