eBugs in Cloud Systems updated HDFS-14473:
------------------------------------------
Description:
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 seem to 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.

An {{IOException}} can mean many different errors, while the error message
indicates that {{receiveBlock()}} is interrupted. Will this mismatch 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.
