Hi, I trying to development for my service using ES.  
Java API doesn't support cat API? I tried to find cat API for java, but can't found it.  
I could try to REST cat API using Java's URLConnection or other REST template libraries, but I don't like it.

Cat is just a REST endpoint which simplifies end user calls.

As a Java dev, you can execute same cat internal calls. Have a look at this package [https://github.com/elastic/elasticsearch/tree/master/core/src/main/java/org/elasticsearch/rest/action/cat](https://github.com/elastic/elasticsearch/tree/master/core/src/main/java/org/elasticsearch/rest/action/cat)

You can't call the APIs from java. You can use the rest controllers as  
references for how you can make the same sequence of calls that they do.
