ClassCastException on Drop table query in apache spark hive - hadoop

Question

I'm using the following hive query :
this.queryExecutor.executeQuery("Drop table user")
and am getting the following exception :
java.lang.LinkageError: ClassCastException: attempting to castjar:file:/usr/hdp/2.4.2.0-258/spark/lib/spark-assembly-1.6.1.2.4.2.0-258-hadoop2.7.1.2.4.2.0-258.jar!/javax/ws/rs/ext/RuntimeDelegate.classtojar:file:/usr/hdp/2.4.2.0-258/spark/lib/spark-assembly-1.6.1.2.4.2.0-258-hadoop2.7.1.2.4.2.0-258.jar!/javax/ws/rs/ext/RuntimeDelegate.class

I saw there have been similar posts here and here but they haven't had any response till now.
Also have looked here but don't think thats a valid course of action in my case.
Whats intriguing is that this is specific when we try to use drop table (or drop table if exists) query.
Hoping to find resolution for the same.

To my knowledge, The above error could be because of sample class with same package structure ie: 'javax.ws.rs.ext.RuntimeDelegate' found in different JARs issue. Class Objects are created and casted at run time. So there is every possibility the the code responsible for triggering DROP syntax , the above class would be used and broken due as it it is found more than once in the classpath.
I have tried DROP and DROP IF EXISTS in chd5 and was working without issue, below are the details of my run:
first run - Hadoop version - 2.6,Hive 1.1.0 and Spark - 1.3.1 (included hive libraries to spark lib)
second run -Hadoop version - 2.6,Hive 1.1.0 and Spark - 1.6.1
Mode of run - cli
scala> sqlContext.sql("DROP TABLE SAMPLE");
16/08/04 11:31:39 INFO parse.ParseDriver: Parsing command: DROP TABLE SAMPLE
16/08/04 11:31:39 INFO parse.ParseDriver: Parse Completed
......
scala>sqlContext.sql("DROP TABLE IF EXISTS SAMPLE");
16/08/04 11:40:34 INFO parse.ParseDriver: Parsing command: DROP TABLE IF EXISTS SAMPLE
16/08/04 11:40:35 INFO parse.ParseDriver: Parse Completed
.....
If Possible please validate DROP commands using a different version of spark lib to narrow down problem scope.
Meanwhile, I am analyzing the jars to find out the linkage where two occurrences of same class 'RuntimeDelegate' existence and will report back to check if the removal of any jar can fix the issue and addition of the jar should recreate the same issue.
