Thomas created YARN-9728:
----------------------------
Summary: ResourceManager REST API can produce an illegal xml
response
Key: YARN-9728
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.
The application will fail 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.
*+Examples of illegals characters in xml 1.0 :+*
* \u0001
* \u0002
* \u0003
* \u0004
_For more information about supported characters :_
