How to migrate/ change Hadoop 1.x maven project to Hadoop 2.x?

0 votes

Currently I have a maven project which is based on Hadoop 1.2.1 and I want to migrate my project from Hadoop 1.2.1 to 2.2. My old dependencies are as follows:

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

I tried to change the version to 2.2, but it is not working. Can anyone help me out in migrating my project to Hadoop 2.2?

In Hadoop 2.2. most of the dependencies of Hadoop-core has been moved to hadoop-client. And also try to specify the version as 2.2.0 for Hadoop jars.

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