>
> Dear HDFS 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-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/BlockReceiver.java
> Line: 1070
> {code:java}
> throw new IOException("Interrupted receiveBlock");{code}
>
> An {{IOException}} can mean many different errors, while the error message indicates that {{receiveBlock()}} 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.
