Finagle - upgrade ClientBuilder() to New APIs version - scala

Question

I have a project with Scala Play - Finagle and ElasticSearch
I am using a Finagle client with the old version of the API, like this:
val client = ClientBuilder()
.codec(Http)
.hosts("localhost:10000,localhost:10001,localhost:10003")
.hostConnectionLimit(1)
.build()
Here is my code:
https://gist.github.com/hectorgool/f217d16e2c15b122d7a7
and works fine, but now i want to upgrade my code to a new APIs version, like this:
val client = Http.newService("localhost:10000,localhost:10001")
The new version of my code is here:
https://github.com/hectorgool/es-client/blob/master/app/lib/FinagleClient.scala
But, now my project does not compile, I have an error with this line(111):
111: val client = clientFactory.apply()()
I don't know how to fix it

Solved
I change this:
val clientFactory: ServiceFactory[HttpRequest, HttpResponse] = ClientBuilder()
.codec(Http())
.hosts(hosts)
.tcpConnectTimeout(1.second)
.hostConnectionLimit(1)
.buildFactory()
for this:
val clientFactory: Service[HttpRequest, HttpResponse] = Http.newService(hosts)
I sumprime this:
val client = clientFactory.apply()()
And i change this:
httpResponse.onSuccess{
response =>
Logger.debug("Received response: " + response)
client.close()
}.onFailure{ err: Throwable =>
Logger.error(err.toString)
client.close()
}
for this:
httpResponse.onSuccess{
response =>
Logger.debug("Received response: " + response)
}.onFailure{ err: Throwable =>
Logger.error(err.toString)
}
the cause of the problem is:
client.close()
because closing the connections
