Subject [jira] [Commented] (HDFS-11696) Fix warnings from Spotbugs in hadoop-hdfs

Yiqun Lin commented on HDFS-11696:
----------------------------------

Hi [~andrew.wang], could you please explain more info of the above problem?  The option {{-nonInteractive}}
and {{-force}} is used under the option {{-format}}, so I did a simple checking for the format
state in following codes:
{code}
     public void setForceFormat(boolean force) {
+      Preconditions.checkState(this == FORMAT);
       isForceFormat = force;
     }
     
@@ -234,6 +238,7 @@ public boolean getInteractiveFormat() {
     }
     
     public void setInteractiveFormat(boolean interactive) {
+      Preconditions.checkState(this == FORMAT);
       isInteractiveFormat = interactive;
     }
{code}
>From my understanding on this, this change will still make current options run okay, right?
Is there some corner cases that I am missing? Please let me know if I am not correct. Thanks,
