> Key: HADOOP-16295
> URL: https://issues.apache.org/jira/browse/HADOOP-16295
> Project: Hadoop Common
> Issue Type: Sub-task
> Reporter: eBugs
> Priority: Minor
>
> Dear Hadoop 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-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileUtil.java
> Line: 1387
> {code:java}
> throw new IOException("replaceFile interrupted.");{code}
>
> An {{IOException}} can mean many different errors, while the error message
> indicates that {{replaceFile()}} is interrupted. This mismatch could be a
> problem. For example, the callers trying to handle other {{IOException}} may
> accidentally (and incorrectly) handle the interrupt. An
> {{InterruptedIOException}} may be better here.
