Thanks Aaron.
Adding Guava jar resolves the issue.

Spark's network-common package depends on guava as a "provided" dependency
in order to avoid conflicting with other libraries (e.g., Hadoop) that
depend on specific versions. com/google/common/base/Preconditions has been
present in Guava since version 2, so this is likely a "dependency not

Hi Frank,
Its a normal eclipse project where I added Scala and Spark libraries as
user libraries.
Though, I am not attaching any hadoop libraries, in my application code I
have following line.
System.setProperty("hadoop.home.dir", "C:\\SB\\HadoopWin")
This Hadoop home dir contains "winutils.ex
Shailesh,
To add, are you packaging Hadoop in your app? Hadoop will pull in Guava. Not
sure if you are using Maven (or what) to build, but if you can pull up your
builds dependency tree, you will likely find com.google.guava being brought in
by one of your dependencies.

Hello,
I double checked the libraries. I am linking only with Spark 1.2.
Along with Spark 1.2 jars I have Scala 2.10 jars and JRE 7 jars linked and
nothing else.
Thanks,

Guava is shaded in Spark 1.2+. It looks like you are mixing versions
of Spark then, with some that still refer to unshaded Guava. Make sure
you are not packaging Spark with your app and that you don't have
other versions lying around.

Hello,
I recently upgraded my setup from Spark 1.1 to Spark 1.2.
My existing applications are working fine on ubuntu cluster.
But, when I try to execute Spark MLlib application from Eclipse (Windows
node) it gives java.lang.NoClassDefFoundError:
com/google/common/base/Preconditions exception.
