Andrew Ash updated SPARK-21757:
-------------------------------
Description:
At the following two places if the {{e.reason}} value contains a single quote
character, then the rendered JSON is invalid.
https://github.com/apache/spark/blob/v2.2.0/core/src/main/scala/org/apache/spark/ui/jobs/AllJobsPage.scala?utf8=%E2%9C%93#L158
https://github.com/apache/spark/blob/v2.2.0/core/src/main/scala/org/apache/spark/ui/jobs/JobPage.scala#L127
A quick fix could be to do replacement of {{'}} with html entity
{noformat}'{noformat} and a longer term fix could be to not assemble JSON
via string concatenation, and instead use a real JSON serialization library in
those two places.
