> Dear YARN 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-tools/hadoop-sls/src/main/java/org/apache/hadoop/yarn/sls/SLSRunner.java
> Line: 894
> {code:java}
> if (!outputFile.exists() && !outputFile.mkdirs()) {
> System.err.println("ERROR: Cannot create output directory "
> + outputFile.getAbsolutePath());
> throw new YarnException("Cannot create output directory");
> }{code}
>
> The exception is triggered when {{run()}} fails to create the output
> directory (as indicated by the {{if}} condition and the error message).
> However, throwing a {{YarnException}} is too general and makes accurate
> exception handling more difficult. Since the error is related to I/O,
> throwing an {{IOException}}, or wrapping an {{IOException}} could be better.
