elasticsearch ElasticsearchIntegrationTest

Indeed, it seems there is a mismatch between the randomizedtesting jar Lucene uses and the one ES uses. Try this in your pom.xml:

    <dependency>        <groupId>org.apache.lucene</groupId>        <artifactId>lucene-test-framework</artifactId>        <version>4.10.2</version>        <scope>test</scope>        <exclusions>            <exclusion>                <artifactId>randomizedtesting-runner</artifactId>                <groupId>                    com.carrotsearch.randomizedtesting                </groupId>            </exclusion>        </exclusions>    </dependency>    <dependency>        <groupId>org.elasticsearch</groupId>        <artifactId>elasticsearch</artifactId>        <version>1.4.0</version>        <scope>test</scope>        <type>test-jar</type>    </dependency>    <dependency>        <groupId>org.elasticsearch</groupId>        <artifactId>elasticsearch</artifactId>        <version>1.4.0</version>        <scope>test</scope>    </dependency>    <dependency>        <groupId>com.carrotsearch.randomizedtesting</groupId>        <artifactId>randomizedtesting-runner</artifactId>        <version>2.1.10</version>        <scope>test</scope>    </dependency>
