Hi all,

I've been trying to clean out the corner cases out of my code in  
elasticsearch, but I'm having a problem with mappings. Is there a function  
within the API which checks if a given Json is a valid mapping without  
calling the REST client?

I find that I get UncategorizedExecutionExceptions when I put certain  
invalid mappings like  
{  
"properties": "string"  
}

I'd like to avoid catching this exception class if possible so that  
debugging is easier since the exception fairly general. I was thinking a  
mapping validator would solve the problem, but I'm definitely fine with  
implementing other solutions if they are available.

Any help would be appreciated.

Thanks,  
Timothy
