----------------------------------
Summary: Web UI's timeline visualizations fails to render if
descriptions contain single quotes
Key: SPARK-15209
URL: https://issues.apache.org/jira/browse/SPARK-15209
Project: Spark
Issue Type: Bug
Components: Web UI
Affects Versions: 1.6.1, 2.0.0
Reporter: Josh Rosen
Assignee: Josh Rosen
If a Spark job's job description contains a single quote (') then the driver
UI's job event timeline will fail to render due to Javascript errors. To
reproduce these symptoms, run
{code}
sc.setJobDescription("double quote: \" ")
sc.parallelize(1 to 10).count()
sc.setJobDescription("single quote: ' ")
sc.parallelize(1 to 10).count()
{code}
and browse to the driver UI. This will currently result in an "Uncaught
SyntaxError" because the single quote is not escaped and ends up closing a
Javascript string literal too early.
I think that a simple fix may be to change the relevant JS to use double quotes
and then to use the existing XML escaping logic to escape the string's contents.
