Problem with running WordCount example 

Hi,

While running the WordCount.java file from hadoop, faced the following error:

Exception in thread "main" java.io.IOException: Error opening job jar: /user/droy/wordcount_hdfs/WordCount.jar
        at org.apache.hadoop.util.RunJar.main(RunJar.java:90)
Caused by: java.util.zip.ZipException: error in opening zip file
        at java.util.zip.ZipFile.open(Native Method)
        at java.util.zip.ZipFile.<init>(ZipFile.java:114)
        at java.util.jar.JarFile.<init>(JarFile.java:133)
        at java.util.jar.JarFile.<init>(JarFile.java:70)
        at org.apache.hadoop.util.RunJar.main(RunJar.java:88)


Here the hdfs directory is : /user/droy/wordcount_hdfs/


Please advise.

Re: Problem with running WordCount example

You should not put the application jar itself on the hdfs (in this case 
hadoop-*-examples.jar).

If you run the following command, <in> and <out> are directories on the 
configured filesystem (which is DFS most of the times):
bin/hadoop jar hadoop-*-examples.jar wordcount <in> <out>
