坑:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/util/StopWatch
at org.apache.hadoop.mapred.FileInputFormat.getSplits(FileInputFormat.java:314)
啊,还是最爱StackOverFlow啊!!!
一直报上面错误,找了半天原因,在sof上看到是版本原因,果然,更换pom.xml版本后,解决了问题!
I solved the problem , actually there was version incompetency so i change hadoop-client 2.6.0 to 2.7.0
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.7.2</version>
</dependency>
