             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.
