我一直在尝试在具有Hadoop 2.7.3和Giraph 1.3.0的Ubuntu服务器上运行Apache Giraph作业。我还尝试在具有较低版本Giraph(1.2 / 1.1)的Hadoop 2.6上运行相同的作业。但是在两种情况下我都会收到以下错误。
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

有没有人遇到过类似的情况？
最佳答案
由于您的hadoop版本，在hadoop 2.6.0中已更改setPingInterval()方法的访问修饰符，将您的hadoop版本降级为2.5.1，即可正常工作。
