------------------------------------------

> a user submitted a mapreduce job with a newline (\n) in the job name. This
> caused the resource manager web ui to get a javascript exception when loading
> the application and scheduler pages and the pages were pretty well useless
> after that since they didn't load everything. Note that this only happens
> when the data is returned in the JS_ARRAY, which is when you get over 100
> applications.
> errors:
> Uncaught SyntaxError: Unexpected token ILLEGAL
> Uncaught ReferenceError: appsData is not defined
> It seems odd that we allow the \n in the job name. It appears we allow it in
> 1.0 also, although when I ran a test the job itself failed in taskrunner.
> 0.23 seems to run the job fine with the \n in the job name.
