I have been trying to run an Apache Giraph job on an Ubuntu server with Hadoop 2.7.3 and Giraph 1.3.0. I have also tried to run the same job on Hadoop 2.6 with lower versions of Giraph (1.2/1.1). But I receive the following error in both the situations.

Exception in thread "main" java.lang.IllegalAccessError: tried to access method org.apache.hadoop.ipc.Client.setPingInterval(Lorg/apache/hadoop/conf/Configuration;I)V from class org.apache.giraph.job.GiraphJob

Has anybody experienced a similar situation ?

its because of your hadoop version, the access modifier of setPingInterval() method has been changed in hadoop 2.6.0, degrade your hadoop version to 2.5.1 and it will work fine.
