here is my source code: ```java @ClusterScope(scope = Scope.SUITE) public class MyExpertScriptEngineTest extends ESIntegTestCase { public MyExpertScriptEngineTest() { System.setProperty(TESTS_CLUSTER, "localhost:9300"); System.setProperty("tests.rest.cluster", "localhost:9200"); } @Override protected Collection> nodePlugins() { return Collections.singleton(ExamplePlugin.class); } } ``` I see that, `nodePlugins` didn't fire. ---

Hey, this looks good from a quick check, we do the same in our tests, except with the CTOR, that should be put into a before method or handed in via properties on the command line. Keep in mind, that ES starts on other than the default ports. Showing the logs from the test might be very useful in a gist. --Alex ---

Hi @spinscale, Can you take a look my test case? > Here is stacktrace: ```java java.lang.IllegalArgumentException: no hosts provided at __randomizedtesting.SeedInfo.seed([FB7A456648DB37AC:E8E928B8F26BEDEF]:0) at org.elasticsearch.client.RestClientBuilder.(RestClientBuilder.java:67) at org.elasticsearch.client.RestClient.builder(RestClient.java:117) at org.elasticsearch.test.ESIntegTestCase.createRestClient(ESIntegTestCase.java:2200) at org.elasticsearch.test.ESIntegTestCase.createRestClient(ESIntegTestCase.java:2184) at org.elasticsearch.test.ESIntegTestCase.getRestClient(ESIntegTestCase.java:2178) at org.elasticsearch.plugin.example.testing.MyExpertScriptEngineTest.testSimulateProcessor(MyExpertScriptEngineTest.java:82) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at com.carrotsearch.randomizedtesting.RandomizedRunner.invoke(RandomizedRunner.java:1737) at com.carrotsearch.randomizedtesting.RandomizedRunner$8.evaluate(RandomizedRunner.java:934) at com.carrotsearch.randomizedtesting.RandomizedRunner$9.evaluate(RandomizedRunner.java:970) at com.carrotsearch.randomizedtesting.RandomizedRunner$10.evaluate(RandomizedRunner.java:984) at com.carrotsearch.randomizedtesting.rules.StatementAdapter.evaluate(StatementAdapter.java:36) at org.apache.lucene.util.TestRuleSetupTeardownChained$1.evaluate(TestRuleSetupTeardownChained.java:49) at org.apache.lucene.util.AbstractBeforeAfterRule$1.evaluate(AbstractBeforeAfterRule.java:45) at org.apache.lucene.util.TestRuleThreadAndTestName$1.evaluate(TestRuleThreadAndTestName.java:48) at org.apache.lucene.util.TestRuleIgnoreAfterMaxFailures$1.evaluate(TestRuleIgnoreAfterMaxFailures.java:64) at org.apache.lucene.util.TestRuleMarkFailure$1.evaluate(TestRuleMarkFailure.java:47) at com.carrotsearch.randomizedtesting.rules.StatementAdapter.evaluate(StatementAdapter.java:36) at com.carrotsearch.randomizedtesting.ThreadLeakControl$StatementRunner.run(ThreadLeakControl.java:368) at com.carrotsearch.randomizedtesting.ThreadLeakControl.forkTimeoutingTask(ThreadLeakControl.java:817) at com.carrotsearch.randomizedtesting.ThreadLeakControl$3.evaluate(ThreadLeakControl.java:468) at com.carrotsearch.randomizedtesting.RandomizedRunner.runSingleTest(RandomizedRunner.java:943) at com.carrotsearch.randomizedtesting.RandomizedRunner$5.evaluate(RandomizedRunner.java:829) at com.carrotsearch.randomizedtesting.RandomizedRunner$6.evaluate(RandomizedRunner.java:879) at com.carrotsearch.randomizedtesting.RandomizedRunner$7.evaluate(RandomizedRunner.java:890) at org.apache.lucene.util.AbstractBeforeAfterRule$1.evaluate(AbstractBeforeAfterRule.java:45) at com.carrotsearch.randomizedtesting.rules.StatementAdapter.evaluate(StatementAdapter.java:36) at org.apache.lucene.util.TestRuleStoreClassName$1.evaluate(TestRuleStoreClassName.java:41) at com.carrotsearch.randomizedtesting.rules.NoShadowingOrOverridesOnMethodsRule$1.evaluate(NoShadowingOrOverridesOnMethodsRule.java:40) at com.carrotsearch.randomizedtesting.rules.NoShadowingOrOverridesOnMethodsRule$1.evaluate(NoShadowingOrOverridesOnMethodsRule.java:40) at com.carrotsearch.randomizedtesting.rules.StatementAdapter.evaluate(StatementAdapter.java:36) at com.carrotsearch.randomizedtesting.rules.StatementAdapter.evaluate(StatementAdapter.java:36) at com.carrotsearch.randomizedtesting.rules.StatementAdapter.evaluate(StatementAdapter.java:36) at org.apache.lucene.util.TestRuleAssertionsRequired$1.evaluate(TestRuleAssertionsRequired.java:53) at org.apache.lucene.util.TestRuleMarkFailure$1.evaluate(TestRuleMarkFailure.java:47) at org.apache.lucene.util.TestRuleIgnoreAfterMaxFailures$1.evaluate(TestRuleIgnoreAfterMaxFailures.java:64) at org.apache.lucene.util.TestRuleIgnoreTestSuites$1.evaluate(TestRuleIgnoreTestSuites.java:54) at com.carrotsearch.randomizedtesting.rules.StatementAdapter.evaluate(StatementAdapter.java:36) at com.carrotsearch.randomizedtesting.ThreadLeakControl$StatementRunner.run(ThreadLeakControl.java:368) at java.lang.Thread.run(Thread.java:745) ``` ---

the problem is not plugin loading, but the rest client initialization ---

So, what's exactly mean of: ```java @Override protected boolean ignoreExternalCluster() { return true; } @Override protected Collection> transportClientPlugins() { return Collections.singleton(ExamplePlugin.class); } @Override protected Collection> nodePlugins() { return Collections.singleton(ExamplePlugin.class); } ``` ---
