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