[jira] [Resolved] (YARN-9534)
TimelineV2ClientImpl.pollTimelineServiceAddress() throws a YarnException
when it is interrupted
[ https://issues.apache.org/jira/browse/YARN-9534?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.

> 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.
