Hi,

I'm currently working with jruby and the java elasticsearch api. To ensure  
a clean index for every testcase, I delete, create and refresh the index  
before every test.  
This work's most of the time but sometimes I get the following exception:

```
org.elasticsearch.action.search.SearchPhaseExecutionException: Failed 

```

> to execute phase [query\_fetch], total failure; shardFailures  
> {[_na_][memento\_test][0]: No active shards}

What I'm doing is basically:

```
    def reset(index_name)
      client.prepare_delete(index_name).execute.action_get
      client.prepare_create(index_name).execute.action_get
      client.prepare_refresh(index_name).execute.action_get
    end

```

Nothing fancy I guess...  
I guess this is a timing problem but I currently can't think of a way to  
work around this.  
Any hints / best practices for these kind of test cleanups?

thanks!

Have you tried to wait for a Green/Yellow cluster status before executing  
the tests/queries?

My 2 cents

heya, not quite, but you hinted me into the right direction. I'm executing  
a HealthRequest with waitForActiveShards(1) now. This seems to work so far
