upgraded to ES 1.0.0.Beta2

Hi,

Thanks again for this plugin - I previously put in a pull request for upgrade and here's another one!

this is a pull request for an upgrade to Elasticsearch 1.0.0.Beta2
It's only very minor changes in the pom and src/main/java/org/elasticsearch/action/updatebyquery/TransportShardUpdateByQueryAction.java

However, I am seeing some failures in the integration tests:
org.elasticsearch.test.integration.updatebyquery.UpdateByQueryTests

When waiting for the cluster to be green, it is timing out and getting a yellow status. If I comment out these lines in the tests, they pass:
        assertThat(clusterHealth.isTimedOut(), equalTo(false));
        assertThat(clusterHealth.getStatus(), equalTo(ClusterHealthStatus.GREEN));
 but I'm not sure why this consistently fails.

It's possibly a change to the cluster setup, or possibly something about my environment.
I'm just wondering if these tests pass for you? I will keep looking in the meantime.

thanks
Bob.
