Summary: Fix "mapred job -history all" command
Key: MAPREDUCE-5392
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5392
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 3.0.0
Reporter: Shinichi Yamashita
Assignee: Shinichi Yamashita
Priority: Minor
When I use an "all" option by "mapred job -history" comamnd, the following
exceptions are displayed and do not work.
{code}
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.
