RM web UI doesn't handle newline in job name
--------------------------------------------
Key: MAPREDUCE-3689
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3689
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.0
Reporter: Thomas Graves
Priority: Blocker
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.
