>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: webhdfs
>    Affects Versions: 2.9.0, 3.0.0-alpha2
>            Reporter: Rushabh S Shah

> Was going through {{JsonUtilClient#toBlockLocation}} code.
> Below is the relevant code snippet.
> {code:title=JsonUtilClient.java|borderStyle=solid}
>  /** Convert a Json map to BlockLocation. **/
>   static BlockLocation toBlockLocation(Map<?, ?> m)
>       throws IOException{
>     ...
>     ...  
>     boolean corrupt = Boolean.
>         getBoolean(m.get("corrupt").toString());
>     ...
>     ...
>   }
> {code}
> According to java docs for {{Boolean#getBoolean}}
> {noformat}
> Returns true if and only if the system property named by the argument exists and is equal to the string "true". 
> {noformat}
> I assume, the map value for key {{corrupt}} will be populated with either {{true}} or {{false}}.
> On the client side, {{Boolean#getBoolean}} will look for system property for true or false.
> So it will always return false unless the system property is set for true or false.
