1.htrace-core-3.0.jar

2.commons-configuration-1.6.jar

3.hadoop-auth-2.6.0.jar

4.hadoop-common-2.6.0.jar

5.hadoop-hdfs-2.6.0.jar

6.hadoop-mapreduce-client-core-2.6.0.jar

遇到这些错误时，添加以上包就可以解决:

java.lang.NoClassDefFoundError: org/htrace/Trace

java.lang.NoClassDefFoundError: org/apache/commons/configuration/Configuration

java.lang.NoClassDefFoundError: org/apache/hadoop/util/PlatformName

java.io.IOException: No FileSystem for scheme: hdfs

java.io.IOException: Incomplete HDFS URI, no host: hdfs://
