java.lang.NoClassDefFoundError: com/google/common when trying to create a Configuration object

I am trying to interact with my HDFS from within java. When I attempt to create a new Configuration object

Configuration conf = new Configuration();

my application throws this error

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/base/Preconditions
    at org.apache.hadoop.conf.Configuration$DeprecationDelta.<init>(
    at org.apache.hadoop.conf.Configuration$DeprecationDelta.<init>(
    at org.apache.hadoop.conf.Configuration.<clinit>(

I have included the hadoop-common-2.0.0-cdh.4.5.0.jar on my java build path and have checked that my hdfs is in fact running hadoop 2.0 cdh 4.5.0.

Am I not including a necessary jar?


Are you using Maven? If not it is advisable to use maven for dependency management.

They have an easy dependency which encapsulates all dependencies:


But this particular error is from guava library which you need to include in your classpath. But my guess is you will hit new issues.
