--------------------------------------------------------------
Digging into it a bit further, the exact error message above was because my
code looked something like this:
{code}
private static LoadingCache<String, Integer> buildCache() {
return CacheBuilder.newBuilder().maximumSize(10000).build(new
MyCacheLoader());
}
{code}
It looks like, in version 11.0 and above of Guava, CacheBuilder has a method of
{{maximumSize(long)}}, but 10.0.1 has a method of {{maximumSize(int)}}, and
that isn't a backwards-compatible bytecode difference.

> Key: FLUME-2286
> URL: https://issues.apache.org/jira/browse/FLUME-2286
> Project: Flume
> Issue Type: Wish
> Reporter: Joshua Hyde
> Priority: Minor
>
> I wrote a custom Sink as a Flume plugin that uses code that leverages the
> {{CacheBuilder}} class provided by Guava. The problem was that my code uses
> Guava 14.0.1, and I ended up with this error:
> {noformat}
> 31 Dec 2013 11:11:45,071 ERROR
> [SinkRunner-PollingRunner-DefaultSinkProcessor]
> (my.package.CustomSink.process:104) - Failed to process events.
> java.lang.NoSuchMethodError:
> com.google.common.cache.CacheBuilder.maximumSize(J)Lcom/google/common/cache/CacheBuilder;

> {noformat}
> Thankfully, I have direct control over the code that uses Guava 14.0.1 and
> can download it to the version used by Flume (10.0.1 at time of writing
> this), but it'd be nice if I didn't have to downgrade my code base for this.
