oozie捕获标准输出&异常capture-output
对于普通的java-action或者shell-action 都是支持的只要标准输出是"k1=v1"这中格式的就行：
现用test.py进行测试：
##test.py
#! /opt/anaconda3/bin/python import re
import os
import sys
import traceback if __name__ == '__main__':
try:
print("k1=v1") print(aaa) ##这里是个故意设置的错误
except Exception as e: print(traceback.format_exc())
exit(0) ##这个地方要特别注意，当异常退出时capture-output将会失效，所以要想获取异常信息，一定要正常退出，然后在decison节点处理错误退出

dryrun=False
jobTracker=108412.server.bigdata.com.cn:8032
nameNode=hdfs://108474.server.bigdata.com.cn:8020

#oozie.action.sharelib.for.spark=spark,hive spark-action
#oozie.action.sharelib.for.sqoop=sqoop,hbase
oozie.wf.application.path=${nameNode}/user/lyy/oozie/test
将以上test.py和workflow.xml放到hdfs的/user/lyy/oozie/test目录下，使用一下命令提交：
oozie job -oozie http://10.8.4.46:11000/oozie -config job.properties -run
另外如果代码中有标准输出，但是格式不是"k=v"类型的，则用el函数wf:actionData无法获取，然而capture-output依旧把标准输出的信息捕获了，存储在oozie元数据表oozie.WF_ACTIONS中data字段存放，这个字段是mediumblob类型不能直接查看，可以通过下面restfulAPI获取json格式的数据，如下：
