Description

When I use an "all" option by "mapred job -history" comamnd, the following exceptions are displayed and do not work.

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -3

This is because a node name recorded in History file is not given "tracker_". Therefore it makes modifications to be able to read History file even if a node name is not given by "tracker_".
In addition, it fixes the URL of displayed task log.
