Being a beginner to hadoop,I started to try out configuring a single node hadoop cluster in ubuntu. After installation and configuration, I worked with the example part with hadoop and it have thrown the following error
hduser1@ubuntu:/usr/local/hadoop$ hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce- examples-2.2.0.jar pi 2 5
java.lang.NoSuchMethodError: org.apache.hadoop.util.ProgramDriver.run([Ljava/lang/String;)I
at org.apache.hadoop.examples.ExampleDriver.main(ExampleDriver.java:74)

I have used Java-7-oracle and Ubuntu 12.04 and followed this post to install and configure hadoop: http://codesfusion.blogspot.in/2013/10/setup-hadoop-2x-220-on-ubuntu.html
The error message means that while the runtime was able to find the class ProgramDriver
, the function run()
is not present.
The most likely reason for this is that you're running an old version of Hadoop that exposed a difference interface in ProgramDriver
. About a year ago this method was renamed to run()
after being called driver()
.
The fix for that would be making sure you're running a recent version of Hadoop.
