Amareshwari Sriramadasu commented on HADOOP-3263:
-------------------------------------------------

Doing not-null check in jobhistory.jsp makes more sense than jobHistory.java, 
since jobHistory.java can truncate the filename (if it exceeds 
max_file_name_size) and jsp file should take care of that.

> job history browser throws exception if job name or user name is null.

> Job history browser throws exception if job name or user name is null.  
> Instead it should print a null string for user/job name if they are null.
