我使用的是ApacheOozie4.3.0版本和Hadoop2.7.3版本
我开发了一个非常简单的oozie工作流,它只需要一个sqoop操作就可以将系统事件导出到mysql表中。
<workflow-app name="WorkflowWithSqoopAction" xmlns="uri:oozie:workflow:0.1">
<start to="sqoopAction"/>
<action name="sqoopAction">
<sqoop xmlns="uri:oozie:sqoop-action:0.2">
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<command>export --connect jdbc:mysql://localhost/airawat --username devUser --password myPwd --table eventsgranularreport --direct --enclosed-by '\"' --export-dir /user/hive/warehouse/eventsgranularreport </command>
</sqoop>
<ok to="end"/>
<error to="killJob"/>
</action>
<kill name="killJob">
<message>"Killed job due to error: ${wf:errorMessage(wf:lastErrorNode())}"</message>
</kill>
<end name="end" />
</workflow-app>
我在hdfs中部署了如下应用程序:
hdfs dfs -ls -R /oozieProject | awk '{ print $8 }'
/oozieProject/workflowSqoopAction
/oozieProject/workflowSqoopAction/README.md
/oozieProject/workflowSqoopAction/job.properties
/oozieProject/workflowSqoopAction/workflow.xml
hdfs dfs -ls -d /oozieProject
drwxr-xr-x - sergio supergroup 0 2017-04-15 14:08 /oozieProject
我已在job.properties中包含以下配置:
# *****************************
# job.properties
# *****************************
nameNode=hdfs://localhost:9000
jobTracker=localhost:8032
queueName=default
mapreduce.job.user.name=sergio
user.name=sergio
oozie.libpath=${nameNode}/oozieProject/share/lib
oozie.use.system.libpath=true
oozie.wf.rerun.failnodes=true
oozieProjectRoot=${nameNode}/oozieProject
appPath=${oozieProjectRoot}/workflowSqoopAction
oozie.wf.application.path=${appPath}
然后我将作业发送到oozie服务器并开始执行它:
oozie job -oozie http://localhost:11000/oozie -config /home/sergio/git/hadoop_samples/hadoop_examples/src/main/java/org/sanchez/sergio/hadoop_examples/oozie/workflowSqoopAction/job.properties -submit
oozie job -oozie http://localhost:11000/oozie -start 0000001-170415112256550-oozie-serg-W
不久之后,在oozie的web控制台中可以看到工作失败:
sqoopaction中出现以下错误消息:
JA017: Could not lookup launched hadoop Job ID [job_local245204272_0008] which was associated with action [0000001-170415112256550-oozie-serg-W@sqoopAction]. Failing this action!
有人能告诉我这个错误吗?

在hadoop中缺少一些配置属性。我也在使用hadoop-2.7.3和oozie-4.3,在过去的5天里遇到了同样的问题。
如前所述配置几个属性,并在我的本地服务器上运行:
yarn-site.xml:
mapred-site.xml:
根据您的设置,用实际值替换属性值。现在重启yarn、hadoop和oozie。
祝你好运。
