RunJar should provide more diags when it can't create a temp file -----------------------------------------------------------------
Key: HADOOP-6614 URL: https://issues.apache.org/jira/browse/HADOOP-6614 Project: Hadoop Common Issue Type: Improvement Components: util Affects Versions: 0.22.0 Reporter: Steve Loughran Priority: Minor When you see a stack trace about permissions, it is better if the trace included the file/directory at fault: {code} Exception in thread "main" java.io.IOException: Permission denied at java.io.UnixFileSystem.createFileExclusively(Native Method) at java.io.File.checkAndCreate(File.java:1704) at java.io.File.createTempFile(File.java:1792) at org.apache.hadoop.util.RunJar.main(RunJar.java:147) {code} As it is, you need to go into the code, discover that it's {{${hadoop.tmp.dir}/hadoop-unjar}}, but you need to know the value of hadoop.tmp.dir to really find out what the problem is. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
