Benjamin Darfler commented on MAPREDUCE-2056:
---------------------------------------------

Seeing the same issue, I get the following stack trace

prompt$ hadoop jar -libjar thirdPartyJar.jar mapreduce.jar input output

Exception in thread "main" java.io.IOException: Error opening job jar: -libjar
	at org.apache.hadoop.util.RunJar.main(RunJar.java:90)
Caused by: java.util.zip.ZipException: error in opening zip file

>          Issue Type: Bug
>    Affects Versions: 0.20.2
>            Reporter: Ron Bodkin
>
> HADOOP-1622 was apparently broken in refactoring (I think in the refactoring that removed JobShell) a few releases ago. e.g., running
> hadoop -libjars lib.jar main.jar Class 
> now tries to run -libjars as a library.
> It would be nice to fix this regression.
