oozie任务调度spark2实例

1、运行环境

CDH:CDH 5.16.1

Java:1.8

scala:2.11.8

spark:2.2.0

oozie:oozie-4.1.0

2、创建spark2目录

hadoop fs -mkdir /user/oozie/share/lib/lib_20190121152411/spark2

上传jar包

hadoop fs -put /opt/cloudera/parcels/SPARK2/lib/spark2/jars/*  /user/oozie/share/lib/lib_20190121152411/spark2

hadoop fs -cp /user/oozie/share/lib/lib_20190121152411/spark/oozie-sharelib-spark-4.1.0-cdh5.16.1.jar /user/oozie/share/lib/lib_20190121152411/spark2

hadoop fs -cp /user/oozie/share/lib/lib_20190121152411/spark/oozie-sharelib-spark.jar /user/oozie/share/lib/lib_20180403101432/spark2 

3、新建job.properties、workflow.xml、目录lib存放需要运行的jar包

其中

job.properties：

nameNode=hdfs://cdh01:8020 jobTracker=cdh01:8032 master=yarn-cluster queueName=default examplesRoot=examples oozie.use.system.libpath=true oozie.wf.application.path=${nameNode}/user/${user.name}/${examplesRoot}/apps/spark2 workflowpath=${nameNode}/user/${user.name}/${examplesRoot}/apps/spark2 userName=root groupsName=supergroup #jars in hdfs oozie.libpath=/user/oozie/share/lib/lib_20190121152411/spark2 oozie.subworkflow.classpath.inheritance=true #oozie url oozieUrl=http://cdh01:11000/oozie/

workflow.xml

<workflow-app xmlns='uri:oozie:workflow:0.5' name='SparkPi'>     <start to="SparkPi" />     <action name="SparkPi">         <spark xmlns="uri:oozie:spark-action:0.1">             <job-tracker>${jobTracker}</job-tracker>             <name-node>${nameNode}</name-node>             <configuration>                 <property>                     <name>oozie.action.sharelib.for.spark</name>                     <value>spark2 </value>                 </property>             </configuration>             <master>${master}</master>             <name>SparkPi</name>             <class>org.apache.spark.examples.SparkPi</class>             <jar>${nameNode}/user/${wf:user()}/${examplesRoot}/apps/spark2/lib/spark-examples_2.11-2.3.0.cloudera3.jar</jar>             <spark-opts> --deploy-mode cluster --driver-memory 2G --executor-memory 4G --num-executors 5 --executor-cores 2</spark-opts>         </spark>         <ok to="end" />         <error to="fail_kill" />     </action>     <kill name="fail_kill">         <message>Job failed, error             message[${wf:errorMessage(wf:lastErrorNode())}]</message>     </kill>     <end name="end" /> </workflow-app>

其中运行时一直出现Error: E0701 : E0701: XML schema error, cvc-complex-type.2.4.a: Invalid content was found starting with element 'name'. One of '{"uri:oozie:spark-action:0.1":master}' is expected.

这个问题是因为我的master和name前后调换了一下，导致出现这个问题，master在前则正常运行。

4、将该文件下的所有文件全部上传到${nameNode}/user/${wf:user()}/${examplesRoot}/apps/spark2所在的目录

5、启动oozie任务

运行成功

遇到的问题:

日志可能在oozie web ui中如果看不到具体日志，可以进8088端口看Applications的日志，到处找找。

问题：
