I modified my pom.xml according to the Spark pom.xml. It is working right now.
Hadoop2 classes are no longer packaged into my jar. Thanks.

Thanks for the information. I changed the dependencies for Spark jars as
follows:
<dependency> <!-- Spark -->
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>1.1.0</version>
<scope>provided</scope>
</dependency>
<dependency> <!-- Spark SQL -->
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.10</artifactId>
<version>1.1.0</version>
<scope>provided</scope>
</dependency>
I don't know how these libraries are built, but I saw Spark has maven pom
files. I think these jars should be built from the corresponding pom files.
These pom files have dependencies on hadoop version 1.0.4. So I don't know
where the hadoop2 jar come from. What follows is a major fragment of my
current dependency tree. I don't know where the hadoop2 classes come into my
built jar.
