hive - Oozie 工作状态停留在 PREP

Question

我正在尝试运行包含 sqoop 和 hive 作业的 oozie 工作流，但是在 Job 的运行状态变为 PREP 后，它转换为 START_RETRY，如图所示

我的 workflow.xml 文件是

<workflow-app xmlns="uri:oozie:workflow:0.5" name="simpleWF">

<kill name="fail">
    <message>error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>

<end name="end"/>

我的 job.properties 文件是

nameNode=hdfs://localhost:8020
jobTracker=localhost:50300
queueName=default
exampleRoot=example
folder= test
outputPath1=
outputPath2=
oozie.use.system.libpath=true
oozie.libpath=/user/oozie/share/lib
oozie.wf.application.path=${nameNode}/user/${user.name}/${exampleRoot}

我在Oozie 工作中发现了一个类似的问题，卡在 PREP 状态下的 START 操作中， 并尝试解决问题，但不知道该怎么做。

我知道我的 namenode 或 jobtracker 地址有问题。

我可以通过 localhost:50070 在浏览器中访问我的名称节点

一段时间后，作业因错误而暂停

JA009: Failed on local exception:

提前致谢。
