maven artifactId hadoop 2.2.0 for hadoop-core

Question

I am migrating my application from hadoop 1.0.3 to hadoop 2.2.0 and maven build had hadoop-core marked as dependency. Since hadoop-core is not present for hadoop 2.2.0. I tried replacing it with hadoop-client and hadoop-common but I am still getting this error for ant.filter. Can anybody please suggest which artifact to use?

previous config :
<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-core</artifactId>
    <version>1.0.3</version>
</dependency>

New Config:

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

Error:

We mainly depend on hdfs api for our application. When we migrated to hadoop 2.X, we were surprised to see the changes in dependencies. We started adding dependencies one at a time. Today we depend on the following core libraries.

hadoop-annotations-2.2.0
hadoop-auth-2.2.0
hadoop-common-2.2.0
hadoop-hdfs-2.2.0
hadoop-mapreduce-client-core-2.2.0

In addition to these we depend on test libraries too. Based on your needs, you may want to include hadoop-hdfs and hadoop-mapreduce-client to the dependencies along with hadoop-common.
