Steve Loughran resolved YARN-9534.
----------------------------------
Resolution: Won't Fix
YarnException is an RTE and not declared on the entire hierarchy, applications
expect it.
We cannot change the failure semantics to switch to a completely new checked
exception hierarchy.
> TimelineV2ClientImpl.pollTimelineServiceAddress() throws a YarnException when
> it is interrupted

> Key: YARN-9534
> URL: https://issues.apache.org/jira/browse/YARN-9534
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: eBugs
> Priority: Minor
>
> Dear YARN developers, we are developing a tool to detect exception-related
> bugs in Java. Our prototype has spotted the following throw statement whose
> exception class and error message indicate different error conditions.
>
> Version: Hadoop-3.1.2
> File:
> HADOOP-ROOT/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/client/api/impl/TimelineV2ClientImpl.java
> Line: 354
> {code:java}
> try {
> Thread.sleep(this.serviceRetryInterval);
> } catch (InterruptedException e) {
> Thread.currentThread().interrupt();
> throw new YarnException("Interrupted while trying to connect ATS");
> }{code}
>
> The exception is triggered when {{pollTimelineServiceAddress()}} is
> interrupted. However, throwing a {{YarnException}} is too general and makes
> accurate exception handling more difficult. If throwing the
> {{InterruptedException}} is not preferred, throwing an
> {{InterruptedIOException}} or wrapping the {{InterruptedException}} could be
> more accurate here.
