-  <description> If job tracker is static the history files are stored

+  <description> The location where jobtracker history files are stored.
+  The value for this key is treated as a URI, meaning that the files 
+  can be stored either on HDFS or the local file system.  If no value is 
+  set here, the location defaults to the local file system, at 
+  file:///${hadoop.log.dir}/history.  If the URI is missing a scheme,
+  fs.default.name is used for the file system.
