Hi all,

I'm running Elasticsearch java client inside a cascading pipe to build an  
index. but it reached an error and brought down cascading workflow.  
look like there's an null pointer exception inside  
IndexRequestBuilder.execute().actionGet();

java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603)  
at java.lang.Thread.run(Thread.java:636)  
17:29:52,617 ERROR VideoCategoriesToIndexFunction:86 -  
org.elasticsearch.ElasticSearchInterruptedException:null-[org.elasticsearch.action.support.AdapterActionFuture.actionGet(AdapterActionFuture.java:47),

....

I sampled a smaller set of data around the place where the exception  
happened. but wasn't able reproduce the error. I'm using elasticsearch  
0.19.4 java client. I have reached this error twice. wondering what could  
be the cause.

Thank you.

Yuhan
