Description

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

try {
  Thread.sleep(this.serviceRetryInterval);
} catch (InterruptedException e) {
  Thread.currentThread().interrupt();
  throw new YarnException("Interrupted while trying to connect ATS");
}

 

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.
