欢迎加入Hadoop超级群:?180941958? ?

? ?

? ? ?之前Oozie都是伪分布式测试,获取的都是本地文件.现在开始在分布式环境下测试,从HDFS中获取文件(所以你的APP也要传入到相应的HDFS路径中).我这里采用的例子是$OOZIE_HOME/examples/apps/map-reduce.其中对job.properties做如下设置:

?nameNode=hdfs://localhost:9000

jobTracker=localhost:9001
queueName=default
examplesRoot=examples

oozie.wf.application.path=${nameNode}/user/${user.name}/${examplesRoot}/apps/map-reduce
outputDir=map-reduce

? ? 之后在控制台通过如下命令提交app job:

??$OOZIE_HOME/bin/oozie job -oozie http://localhost:11000/oozie -config /home/guoyun/hadoop/oozie-2.3.2-cdh3u2/examples/apps/map-reduce/job.properties -run

?

? 但碰到以下异常:
