Hi,
I have been running a simple Spark app on a local spark cluster and I came
across this error.
Exception in thread "main" java.lang.NoSuchMethodError:

While looking into this I found out that Guava was downgraded to version 11
in this PR.
https://github.com/apache/spark/pull/1610
In this PR OpenHashSet.scala:261 line hashInt has been changed to hashLong.
But when I actually run my app, "java.lang.NoSuchMethodError:
com.google.common.hash.HashFunction.hashInt" error occurs,
which is understandable because hashInt is not available before Guava 12.
So, I''m wondering why this occurs?
Cheers
