SYMPTOM: While integrating Storm 1.0.1 to Elastic Search 5.0.0, the following error is observed:

Exception in thread "main" java.lang.NoClassDefFoundError: org/elasticsearch/common/base/Preconditions 
at org.apache.storm.elasticsearch.common.EsConfig.<init>(EsConfig.java:62)

Following were the maven dependencies:
<dependency> 
<groupId>org.apache.storm</groupId> 
<artifactId>storm-core</artifactId> 
<version>1.0.2</version> 
<exclusions> 
<exclusion> 
<groupId>org.slf4j</groupId> 
<artifactId>log4j-over-slf4j</artifactId> 
</exclusion> 
</exclusions> 
</dependency> 

<dependency> 
<groupId>org.elasticsearch</groupId> 
<artifactId>elasticsearch</artifactId> 
<version>5.0.0</version> 
</dependency> 

<dependency> 
<groupId>org.apache.storm</groupId> 
<artifactId>storm-elasticsearch</artifactId> 
<version>1.0.2</version> 
</dependency>
ROOT CAUSE: Apache libraries were used to compile/package the topology instead of using Hortonworks repository RESOLUTION: Please add the Hortonworks repository in the pom.xml:
<repositories> 
<repository> 
<id>hortonworks</id> 
<url>http://repo.hortonworks.com/content/groups/public/</url> 
</repository> 
</repositories>
Then change the storm artifact versions, which should be in this format: <apache_version>.<HDP-version> For example, for 'storm-core' in HDP 2.5.0.0, version would be 1.0.1.2.5.0.0-1245. Similarly, for 'storm-elasticsearch' it would be: 1.0.1.2.5.0.0-1245 (for HDP 2.5.0.0). Please find the version corresponding to your HDP here: http://repo.hortonworks.com/content/groups/public/org/apache/storm/
