> Dear HDFS developers, we are developing a tool to detect exception-related
> bugs in Java. Our prototype has spotted a few {{throw}} statements whose
> exception class does not accurately describe why they are thrown. This can be
> dangerous since it makes correctly handling them challenging. For example, in
> an old bug, HDFS-8224, throwing a general {{IOException}} makes it difficult
> to perform data recovery specifically when a metadata file is corrupted.
