-----------------------------------------------------------
[~ste...@apache.org] Thanks for the comment. I downloaded the hadoop-3.3.2
binary and I could see that the guava JARs in there are guava-27.0-jre.jar and
hadoop-shaded-guava-1.1.1.jar. I read that hadoop injects its JARs into spark
app classpath. Based on seeing guava-14.0.1.jar in the classpath and JAR's
presence in the Spark binary with hadoop
(spark-3.3.2-bin-hadoop3/jars/guava-14.0.1.jar) I ended up assuming it's
Hadoop. Let me reach out to the Spark community, I see that they are
referencing the older guava version we're talking about.

> Spark application's dependency conflicts with Hadoop's dependency

> Key: HADOOP-18670
> URL: https://issues.apache.org/jira/browse/HADOOP-18670
> Project: Hadoop Common
> Issue Type: Bug
> Components: common
> Affects Versions: 3.3.2
> Reporter: Kiran N
> Priority: Blocker
>
> The issue I'm going to describe happens with the distribution: Spark 3.3.2
> (git revision 5103e00c4c) built for Hadoop 3.3.2
> Based on [this ticket|https://issues.apache.org/jira/browse/HADOOP-11804], as
> per my understanding, from Hadoop v3, there shouldn't be any conflict between
> the Hadoop's and Spark app's dependencies. But, I see a runtime failure with
> my spark app because of this conflict. Pasting the stack trace below:
> {{Caused by: java.lang.NoSuchMethodError:
> com.google.common.collect.Sets.newConcurrentHashSet()Ljava/util/Set;}}
> {{ at org.apache.cassandra.config.Config.<init>(Config.java:102)}}
> {{ at
> org.apache.cassandra.config.DatabaseDescriptor.clientInitialization(DatabaseDescriptor.java:288)}}

> My Spark app has a transitive dependency on Guava library. It depends on
> cassandra-all lib, which does on guava lib. The jar guava-14.0.1 that comes
> in "spark-3.3.2-bin-hadoop3/jars" directory is a decade old and doesn't have
> Sets.newConcurrentHashSet() method. I'm able to run the spark app
> successfully by deleting that old version of guava jar from /jar directory
> and by including a recent version in my project's pom.xml.
