hadoop 2.2 + jdk1.7 运行wordcount例子
hadoop jar hadoop-mapreduce-examples-2.2.0.jar wordcount /word /ws
报错：
org.apache.hadoop.mapred.TaskAttemptListenerImpl: Diagnostics report from attempt_1449733659077_0001_m_000000_0: Error: java.lang.ClassCastException: org.apache.hadoop.mapreduce.lib.input.FileSplit cannot be cast to org.apache.hadoop.mapred.InputSplit
请各位高手指点
Hadoop2.6.0运行自带WordCount报错
Win7 运行Hadoop WordCount 报错
运行hadoop wordcount 时候报错解决办法
