What is equivalent to hadoop-core-xxx.jar in hadoop 2.7.1

Question

I am working on Stanford's GPS (graph processing system) framework for distributed processing of graphs. The framework uses hadoop. As per GPS documentation, installing GPS requires copying hadoop-core-xxx.jar file to be copied in its libs directory. But, I found that hadoop-core-xxx.jar is not present in hadoop 2.7.1. What is equivalent to the hadoop core file in 2.7.1 version?

Thanks in advance...

check for hadoop-mapreduce-client-core-xxx.jar – Ravindra babu Nov 18 '15 at 17:06 — Ravindra babu, Nov 18 '15 at 17:06

You're looking for hadoop-common. Here's hadoop-common-2.7.1.

You can download the necessary hadoop-core jar file from here. I'm using it with hadoop 2.6, it must work with 2.7.1 as well.

I get an error with earlier versions: HDFS IO error org.apache.hadoop.ipc.RemoteException: Server IPC version 9 cannot communicate with client version 4 – Thiago Figueiro Mar 28 '16 at 08:11
I got the same error as Thiago. This is not a working solution. – Liu Siyuan Feb 17 '18 at 18:20
