Hive Solr Storage handler Httpclient error - hadoop

Question

I developed Hive solrCloud storage handler, when I run select statement hive is throwing below error:
Exception in thread "main" java.lang.VerifyError: Bad return type

Is there any jar I need to update in class path?
PS: I don't have write access to add any jar in Hadoop or hive lib directory.
System configuration:
Hive 0.13, solrcloud 5.2.

There is an open issue in JIRA for solrj httpclient version conflict. The root cause of this issue is httpclient library version conflict in hadoop class path. The solrj client is not getting initialized by right version of httpclient.
Initializing solrj client with default Httpclient should resolve this issue.
e.g.
SystemDefaultHttpClient httpClient = new SystemDefaultHttpClient();
this.server = new CloudSolrClient(url,httpClient);
You can export hadoop class path to add additional jar files to classpath. Check blog for adding jars to mapreduce job classpath.
export HADOOP_CLASSPATH=/xxx/noggit-0.6.jar:/xxx/httpclient-4.5.1.jar
