[ERROR]   
[ERROR]   The project groupId:hadoop:master-SNAPSHOT (/Users/me/code/p/java/hadoop-programs/hadoop-programs/pom.xml)

    <modelVersion>4.0.0</modelVersion>

    <groupId>groupId</groupId>
    <artifactId>hadoop</artifactId>
    <version>master-SNAPSHOT</version>
    <packaging>jar</packaging>

    <dependencies>
        <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-core</artifactId>
            <version>1.0.3</version>
            <type>jar</type>
            <systemPath>/usr/local/Cellar/hadoop/1.0.3/libexec/hadoop-core-1.0.3.jar</systemPath>

A lot of the stuff in hadoop-core have moved to hadoop-client in newer versions, use -

    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-hdfs</artifactId>
        <version>2.4.1</version>
    </dependency>

use this : 

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-core</artifactId>
    <version>0.20.2</version>
</dependency>
