have used eclipse to export the file and then got following error
hadoop-user$ bin/hadoop jar
wordcountsmp/wordcount.jarorg.apache.hadoop.examples.WordCount input output
Exception in thread "main" java.io.IOException: Error opening job jar:

Caused by: java.util.zip.ZipException: error in opening zip file

I tried following
java -jar xf wordcountsmp/wordcount.jar
and got the error
Unable to access jar file xf
my jar file size is 5kb. I am feeling somehow eclipse export in macOS is not
creating appropriate jar.
