------------------------------------
Hi [~anu] Thanks for catching up that, that is not my intention. It makes sense
to create another JIRA to review these imports and make sure we did not bring
any unnecessary imports, fix wildcard imports etc. Please feel free to assign
that task to me.

> There are several problems
> # Http clients in {{OzoneVolume}}, {{OzoneBucket}} and {{OzoneClient}} are
> created per request, per [Reuse of HttpClient
> instance|http://hc.apache.org/httpclient-3.x/performance.html#Reuse_of_HttpClient_instance]
> doc, proposed to reuse the http client instance to reduce the over head.
> # Some resources in these classes were not properly cleaned up. E.g the http
> connection, HttpGet/HttpPost requests.
>
> This jira's purpose is to fix these issues and investigate how we can improve
> the client.
