hi all :  
I read the elasticsearch's source code. Recently I want to run the test method TransportClientBackwardsCompatibilityIT.testSniffnode, but it is always report one issue.

```
First, the version is 2.4.5, jvm is 1.8.

```

Here is my test procedures:  
1. I download elasticsearch-2.4.5.tar.gz that can run. It is a distribution.  
2. i run the externalnodeservice's main method at the package org.elasticsearch.test, it is source code that imported in idea.  
3.Then I switch from package org.elasticsearch.test to package org.elasticsearch.bwcompat. Then I run TransportClientBackwardsCompatibilityIT.testSniffmode.Before I run it, i edit the configuration, enter some paramater in vm options "-Dtests.bwc.version=2.4.5 -Dtest.bwc=true -Dtest.bwc.path=/home/benhairui/Documents/java/ -ea -Dtests.security.manager=false " .

```
 But, I always get one issue.

```
