--------------------------------------------------
Summary: CommitLogArchiver.construct() throws a RuntimeException
when it failed to create a directory
Key: CASSANDRA-15116
URL: https://issues.apache.org/jira/browse/CASSANDRA-15116
Project: Cassandra
Issue Type: Bug
Reporter: eBugs in Cloud Systems
Dear Cassandra 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.
Since we are not very familiar with Cassandra's internal work flow, could you
please help us to verify if this is a bug, i.e., will the callers have trouble
handling the exception, and will the users/admins have trouble diagnosing the
failure?
Version: Cassandra-3.11 (commit: 123113f7b887370a248669ee0db6fdf13df0146e)
File:
CASSANDRA-ROOT/src/java/org/apache/cassandra/db/commitlog/CommitLogArchiver.java
Line: 110
{code:java}
throw new RuntimeException("Unable to create directory: " + dir);{code}
Reason: {{RuntimeException}} is usually used to represent errors in the program
logic (think of one of its subclasses, {{NullPointerException}}), while the
error message indicates that {{construct()}} failed to create a directory. Will
this mismatch be a problem? For example, will the callers miss the possibility
that {{construct()}} can fail to create a file because it does not throw any
{{IOException}}? Or, will the callers try to handle other {{RuntimeException}}
accidentally (and incorrectly) handle the directory creation failure?
