> Jericho java.lang.IllegalStateException: StreamedText position 10773 has been
> discarded.
> This would cause some embedded JavaScript rewriting to fail.
> To reproduce:
> 1. Set Yarn
> 2. Get Yarn UI through Knox.
> 3. Add more than 10 jobs (any type, Spark, Oozie, Mapreduce, etc).
> 4. Before around 10 the rewriting works but after that it doesn't..
> I debugged this into a call to
> org.apache.hadoop.gateway.filter.rewrite.impl.html.HtmlFilterReaderBase
> Recent code added to rewrite JavaScript is calling:
> String tagType = stack.peek().getTag().getAttributeValue("type");
> Which would failed with the IllegalException in the logs.
> Since we are processing Script and most of it is JavaScript, do we need this
> check??
> Removing this call and JSTYPES.contains(tagType) seem to fix the issue.
