Error while install hadoop on mac

I was trying to install hadoob on mac. I got the following error. What could be the issue?

hadoop-0.20.203.0 administrator$ bin/hadoop jar hadoop-*-examples.jar grep input output 'dfs[a-z.]+'

Exception in thread "main" java.io.IOException: Error opening job jar: hadoop-*-examples.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:127)
    at java.util.jar.JarFile.<init>(JarFile.java:135)
    at java.util.jar.JarFile.<init>(JarFile.java:72)

I had a similar issue with an example from the book Hadoop In Action. It turns out either the book had it wrong or the example jars now have a different naming scheme. In any case, your command should now begin with:

bin/hadoop jar hadoop-examples-*.jar
