>  I found a malformed error message when setting 
> dfs.domain.socket.disable.interval.seconds to a negative value.
>  Reproduction:
>   Set the following HDFS configuration:
>   <property>
>     <name>dfs.domain.socket.disable.interval.seconds</name>
>     <value>-1</value>
>   </property>
>   or:
>   <property>
>     <name>dfs.domain.socket.disable.interval.seconds</name>
>     <value>-4294967296</value>
>   </property>
>   Then start HDFS and run a simple HDFS client operation with short-circuit 
> read enabled.
>   Actual result:
>   The client fails with:
>   java.lang.IllegalArgumentException: 
> dfs.domain.socket.disable.interval.secondscan't be negative.
>   The message is malformed: "secondscan't" is missing a space.
>   Expected result:
>   The error message should be readable, for example:
>   dfs.domain.socket.disable.interval.seconds can't be negative.
>   Reproduced locally:
>   - Negative value case failed.
>   - Normal value dfs.domain.socket.disable.interval.seconds=600 passed.
