    org.apache.hadoo         


        

Answer 1

For Hadoop 2.2.0, the corresponding package name should be as follows (2014.05.27):

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-common</artifactId>
    <version>2.2.0</version>
</dependency>
<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-mapreduce-client-core</artifactId>
    <version>2.2.0</version>
</dependency>
<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-hdfs</artifactId>
    <version>2.2.0</version>
</dependency>

http://mvnrepository.com/artifact/org.apache.hadoop/hadoop-mapreduce-client-core/2.2.0
http://mvnrepository.com/artifact/org.apache.hadoop/hadoop-hdfs/2.2.0

Answer 2

Most of hadoop-core dependencies can be found in hadoop-client:

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-client</artifactId>
    <version>2.2.0</version>
</dependency>
