eBugs in Cloud Systems updated HDFS-14472:
------------------------------------------
Description:
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 seem to 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.

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). Will this mismatch be a problem? For example, the
callers trying to handle other {{FileNotFoundException}} may accidentally (and
incorrectly) handle the malformed path.
