I got this error

```
    java.util.concurrent.ExecutionException: 

```

org.elasticsearch.transport.RemoteTransportException:  
[Sigyn][inet[/10.160.14.67:8600]][search]

and the stack trace was just of how I called execute() on the request

```
    // execute the request
    SearchResponse response;
    try {
        response = request.execute().get();
    } catch (ExecutionException e) {
        throw new RuntimeException(e);
    } catch (InterruptedException e) {
        throw new UncheckedInterruptedException(e);
    }

```

In order to find the root cause of this exception, I had to  
set logger.action=TRACE to be able to find that it was actually a full  
thread pool queue.

2013-10-22 16:12:57,623 -0400 TRACE [elasticsearch[Rawhide  
Kid][transport\_server\_worker][T#4]{New I/O worker #21}] search.type -  
[Rawhide Kid] Error during transport action execution.  
org.elasticsearch.common.util.concurrent.EsRejectedExecutionException:  
rejected execution of  
[org.elasticsearch.action.search.type.TransportSearchTypeAction$BaseAsyncAction$2]  
at  
org.elasticsearch.common.util.concurrent.EsAbortPolicy.rejectedExecution(EsAbortPolicy.java:35)  
at  
java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:821)  
at  
java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1372)

Why was it that the EsRejectedExecutionException didn't show up in the  
stack trace of the RemoteTransportException that showed up in my client  
code?

Best,

Justin

Hey,

the EsRejectedExecutionException was wrapped in a RemoteTransportException  
because it needed to be send over the wire. Not sure on the top of my head,  
but maybe the ExceptionsHelper class has a helper methods for unwrapping.
