> URL: https://issues.apache.org/jira/browse/YARN-9728
> Project: Hadoop YARN
> Issue Type: Bug
> Components: api, resourcemanager
> Affects Versions: 2.7.3
> Reporter: Thomas

> When a spark job throws an exception with a message containing a character out of the range supported by xml 1.0, then
> the application fails and the stack trace will be stored into the {{diagnostics}} field. So far, so good.
> But the issue occurred when we try to get application information with the ResourceManager REST API
> The xml response will contain the illegal xml 1.0 char and will be invalid.
