eBugs created YARN-9534:
---------------------------
Summary: 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
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. Throwing an
{{InterruptedIOException}} or wrapping the {{InterruptedException}} could be
more accurate here.
