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:

Maven dependencies can be got from this link. As far as hadoop-core dependies goes, hadoop-core was the name for hadoop 1.X and just renaming the version to 2.X wont help. Also in a hadoop 2.X project using the hadoop 1.X dependency gives an error like

Caused by: org.apache.hadoop.ipc.RemoteException: Server IPC version 9 cannot communicate with client version 4

Thus it is suggested not to use it. I have been using the following dependencies in my hadoop

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-client</artifactId>
    <version>2.7.1</version>
</dependency>
<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-hdfs</artifactId>
    <version>2.7.1</version>
</dependency>
<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-mapreduce-client-core</artifactId>
    <version>2.7.1</version>
</dependency>
<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-mapreduce-client-jobclient</artifactId>
    <version>2.7.1</version>
</dependency>
<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-mapreduce-client-common</artifactId>
    <version>2.7.1</version>
</dependency>
<dependency>

You can try these.

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

Try with these artifacts, word fine on my sample project wordcount

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

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-core</artifactId>
    <version>1.2.1</version>
</dependency>
