In my case below lines of code in pom.xml in Maven project worked on Mac.

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>2.0</version>
    <configuration>
      <shadedArtifactAttached>true</shadedArtifactAttached>
    </configuration>
    <executions>
      <execution>

        <goals>
          <goal>shade</goal>

This is a file on the local disk that is being created (to unpack your job jar into), not in HDFS. Check you have permissions to mkdir this directory (try it from the command line)
