> 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 {{checkArgument}} to the existing class {{org.apache.hadoop.util.Preconditions}}
> +The plan is as follows+
>  * implement {{org.apache.hadoop.util.Preconditions.checkArgument}} 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.
>  * We need the change to be easily to be backported in 3.x.
> A previous jira HADOOP-17126 was created to replace CheckNotNull. HADOOP-17930 is created to implement checkState.
