-----------------------------------
Summary: Display correct error message when accessing REST API
with an unknown app Id
Key: SPARK-12399
URL: https://issues.apache.org/jira/browse/SPARK-12399
Project: Spark
Issue Type: Bug
Components: Web UI
Affects Versions: 1.5.2
Reporter: Carson Wang
Priority: Minor
I got an exception when accessing the below REST API with an unknown
application Id.
/api/v1/applications/xxx/jobs
Instead of an exception, I expect an error message "no such app: xxx" which is
a similar error message when I access "/api/v1/applications/xxx"
{code}
org.spark-project.guava.util.concurrent.UncheckedExecutionException:
java.util.NoSuchElementException: no app with key xxx
