> 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.

> 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.
