Dick King commented on MAPREDUCE-1554:
--------------------------------------
The current code in the job history browser claims to search job names for
keyWORDS in the instructions it paints on the line beneath the search box, but
it actually searches for substrings. Therefore, if a job's job name is
{{clockwork orange}} but your search key is {{work or}} , the job matches the
search.
Which do you think is more desirable? Do you people out there in cyberspace
think that we should change the documentation to match the code, or the code to
match the documentation?

> If user name contains underscore as part of it, then searching of jobs based
> on user name on job history web UI doesn't work. This is because in code,
> everywhere {code}split("_"){code} is done on history file name to get user
> name. And other parts of history file name also should *not* be obtained by
> using split("_").
