Troubleshooting message for RunJar (bin/hadoop jar)
---------------------------------------------------
Key: HADOOP-464
URL: http://issues.apache.org/jira/browse/HADOOP-464
Project: Hadoop
Issue Type: Improvement
Components: util
Reporter: Michel Tourn
Attachments: runjar.patch
Many users get this exception when using bin/hadoop
There are various reasons:
HADOOP_CONF_DIR or HADOOP_HOME misconfigured.
"hadoop jar" parameter incorrect
So the patch displays the path of the jar it is trying to open if this fails:
Problem while opening hadoop job jar: /home/build/hadoop-streaming.jar
Exception in thread "main" java.util.zip.ZipException: error in opening zip file
at java.util.zip.ZipFile.open(Native Method)
