> Key: HBASE-22371
> URL: https://issues.apache.org/jira/browse/HBASE-22371
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.1.4
> Reporter: eBugs in Cloud Systems
> Priority: Minor
>
> Dear HBase 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 HBase's internal work flow,
> could you please help us 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: HBase-2.1.4
> File:
> HBASE-ROOT/hbase-common/src/java/org/apache/hbase/utils/DynamicClassLoader.java
> Line: 110-111
> {code:java}
> throw new RuntimeException("Failed to create local dir " + localDir.getPath()
> + ", DynamicClassLoader failed to init");{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 {{initTempDir()}} failed to create a
> directory. Will this mismatch be a problem? For example, will the callers
> miss the case where {{initTempDir()}} fails to create a directory? Or, will
> the callers try to handle other {{RuntimeException}} accidentally (and
> incorrectly) handle the directory creation failure?
