----------------------------------
Summary: Jobs page fails to load when executor removed event's
reason contains single quote
Key: SPARK-21757
URL: https://issues.apache.org/jira/browse/SPARK-21757
Project: Spark
Issue Type: Bug
Components: Web UI
Affects Versions: 2.2.0
Reporter: Andrew Ash
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 {{'}} 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.
