---------------------------------
Resolution: Not A Problem
> FSImageHandler.getPath() throws a FileNotFoundException when the path is
> malformed
> ----------------------------------------------------------------------------------

> Key: HDFS-14472
> URL: https://issues.apache.org/jira/browse/HDFS-14472
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: eBugs
> Priority: Minor
>
> 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 indicate different error conditions.
>
> Version: Hadoop-3.1.2
> File:
> HADOOP-ROOT/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/tools/offlineImageViewer/FSImageHandler.java
> Line: 179-180
> {code:java}
> throw new FileNotFoundException("Path: " + path + " should " +
> "start with " + WEBHDFS_PREFIX);{code}
>
> A {{FileNotFoundException}} means that a target file cannot be found.
> However, the error message indicates that the path is malformed (instead of
> well-formed but pointing to no file). This mismatch could be a problem. For
> example, the callers trying to handle other {{FileNotFoundException}} may
> accidentally (and incorrectly) handle the malformed path.
