---------------------------------------------

If it helps, I have already added the required support via this pull request 
(to Thrift project).

[https://github.com/apache/thrift/pull/2439]

I will also include the same helper when I create pull request for adding S3 
read optimization in a few days.

> As part In order to replace Guava Preconditions, we need to implement our own 
> versions of the API.
>  This Jira is to add the implementation {{checkState}} to the existing class 
> {{org.apache.hadoop.util.Preconditions}}
> +The plan is as follows+
>  * implement {{org.apache.hadoop.util.Preconditions.checkState}} with the 
> minimum set of interface used in the current hadoop repo.
>  * we can replace {{guava.Preconditions}} by 
> {{org.apache.hadoop.util.Preconditions}} once all the interfaces have been 
> implemented (both this jira and HADOOP-17929 are complete).
>  * We need the change to be easily to be backported in 3.x.
> previous jiras:
>  * HADOOP-17126 was created to implement CheckNotNull.
>  * HADOOP-17929 implementing checkArgument.
