This project forked from huge-data/cdh5-demo
CDH5使用示例。
将cdh5-demo-0.0.1-SNAPSHOT.jar拷贝到CDH5集群主机的/opt/cloudera/parcels/CDH/jars/目录下。
注意：maven打的jar文件，不能含有以来包。
sudo -u hdfs hadoop jar /opt/cloudera/parcels/CDH/jars/cdh5-demo-0.0.1-SNAPSHOT.jar zx.soft.wordcount.WordCountMain /user/hdfs/input /user/hdfs/output1
或者
sudo -u hdfs hadoop jar /opt/cloudera/parcels/CDH/jars/cdh5-demo-0.0.1-SNAPSHOT.jar zx.soft.wordcount.WordCountMain input output2
注意：因为是在hdfs用户下执行命令的，所以目录input就是/user/hdfs/input。
