Hello,

I try to shrink an index with Curator on a single node cluster but it fails due to cluster health being yellow which is expected when you have only one node.

> Exception: Unable to proceed with shrink action. Cluster health is not "green"

Should I configure `continue_if_exception: True` or is there a better way ?

Below is my action.

```

Curator will not ever attempt a shrink on a cluster that has a yellow state. In the future, it may check to see if only the _index_ is green, and proceed with a shrink, but for now, it will not.

Thanks.  
It's OK because I have an alternative here by deleting the index and let elastalert re-create it.
