Tsuyoshi Ozawa commented on HDFS-8043:
--------------------------------------

[~brahmareddy] thanks for your updating.
{code}
-    if (deleteDfsDir) {
+    if (deleteDfsDir && base_dir != null) {
         base_dir.delete();
     } else {
+      if (base_dir != null) {
         base_dir.deleteOnExit();
+      }
     }
{code}

The condition statements look complex. Could you fix it not to use nested 
if-else statement?
