How to add hadoop dependency via Maven? I have hadoop installed and present in my IDE project library
Solution 1
use this :
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-core</artifactId>
<version>0.20.2</version>
</dependency>
Solution 2
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>

- I have hadoop installed on my system(I am using Mac 10.7)
- I am using Intellij IDEA as IDE and my hadoop project has listed hadoop*.jar as dependency
- When I do
mvn install
, it fails with the following error
