Subject [jira] Commented: (HADOOP-5834) Job History log file format is not friendly for external tools.
Date Thu, 21 May 2009 18:09:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12711737#action_12711737
] 

Philip Zeyliger commented on HADOOP-5834:
-----------------------------------------

What do you mean by "event logs are used for JobTracker restart"?

I'd like to get at these objects in a structured way; i.e., I don't want to parse them from
a String.  Will a log4j logger let me do that?

> Currently, parsing the job history logs with external tools is very difficult because
of the format. The most critical problem is that newlines aren't escaped in the strings. That
makes using tools like grep, sed, and awk very tricky.
