Ahmed Hussein updated HADOOP-17930:
-----------------------------------
    Description: 
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.
