Elasticsearch :found jar hell in test classpath

Question

I want to perform unit testing in Elasticsearch for that I am using Java-test-framework
I am using Elasticsearch-1.6.0 and referring to these link for help https://www.elastic.co/guide/en/elasticsearch/reference/1.6/using-elasticsearch-test-classes.html https://github.com/elastic/elasticsearch/blob/master/core/src/test/java/org/elasticsearch/action/search/SearchRequestBuilderTests.java

here is the code

class CampaignESTest extends ESTestCase {    def getCLient():MockTransportClient={      val settings = Settings.builder()                 .put(Environment.PATH_HOME_SETTING.getKey(), Files.createTempDir().toString())                 .build();      val client = new MockTransportClient(settings);        client   }  }  class CampaignTestSearch extends PlaySpec{   val client=new CampaignESTest  val response = client.prepareSearch("dbtest")       .setTypes(CAMPAIGN_COLLECTION_NAME)       .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)       .addFields("uuid","campaignName","artworkID","activationDate","_source")       .setQuery(query)       .execute()       .actionGet()   } 

I am getting these exceptions

How can these exception will be resolved ? also I have tried the solution given here Java Jar hell Runtime Exception Bit when i try to create a class JarHell in org/elasticsearch/bootstarp package it won't let me create it saying type already exists I also tried searching the Class but did not found ,please guide

Answer 1

As @Val observes, a test framework for ES v5 won't work with ES v1.

Why not upgrade to a newer version of ES?

As I recall, the old v1 has some serious security flaws. Plus ES 5 has better performance, etc.

The other thing you can do is decouple your tests from the exact ES version, by using an http library like Jest or ESJC.
