Alexander Veit created HADOOP-9595:
--------------------------------------
Summary: Error when error message should be printed to stderr
Key: HADOOP-9595
URL: https://issues.apache.org/jira/browse/HADOOP-9595
Project: Hadoop Common
Issue Type: Bug
Components: bin
Affects Versions: 1.2.0
Reporter: Alexander Veit
RunJar contains the lines
{code}
if (!file.exists() || !file.isFile()) {
System.err.println("Not a valid JAR: " + file.getCanonicalPath());
System.exit(-1);
}
{code}
This code fails with
{quote}
Exception in thread "main" java.io.IOException: Invalid argument
at java.io.WinNTFileSystem.canonicalize0(Native Method)
at java.io.Win32FileSystem.canonicalize(Win32FileSystem.java:414)
at java.io.File.getCanonicalPath(File.java:589)
at org.apache.hadoop.util.RunJar.main(RunJar.java:85)
{quote}
A possible fix is
{code}
if (!file.exists() || !file.isFile()) {
System.err.println("Not a valid JAR: " + file);
System.exit(-1);
}
{code}
