describe why they are thrown
eBugs created HDFS-14486:

Summary: Some exception classes do accurately describe why they are thrown
Key: HDFS-14486
URL: https://issues.apache.org/jira/browse/HDFS-14486
Project: Hadoop HDFS
Issue Type: Bug
Reporter: eBugs
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.
