Include <tt> tag in hive.query.string when sending to the jobtracker
--------------------------------------------------------------------

                 Key: HIVE-754
                 URL: https://issues.apache.org/jira/browse/HIVE-754
             Project: Hadoop Hive
          Issue Type: Improvement
            Reporter: Adam Kramer


When a hive job is running in Hadoop, the jobtracker page has a link to the job.xml page (really
jobdetails.jsp).

On this page, hive.query.string is listed, so we can see what's going on with that query (in
case it's using lots of resources).

However, the query is totally unreadable on that page, because HTML spec strips out the newlines
and whitespace. Those are actually included in the HTML _source_ (if you 'view source' on
the page, the query is clear and pretty).

If, however, we were to wrap the whole hive.query.string argument in <tt> </tt>
tags, Apache would format it correctly on the job tracker page, and make understanding what's
going on a whole lot easier.

I filed this improvement in Hadoop Common, https://issues.apache.org/jira/browse/HADOOP-6193
, because I think that ALL of the options should be provided in whitespace-preserving monowidth
text, but on the chance they mark it "won't fix," I think it's extra-special-important for
the case of hive.query.string.
