OOZIE REST API RERUN - START作业功能不起作用
您好, 我想启动Oozie的REST API(Oxie版本4.0.0在CDH 5.3.1中),但作业无法启动或重新运行。
使用Google的ADVANCED REST API启动:
PUT {namenode}:11000/oozie/v1/job/0000001-150528075707705-oozie-oozi-W?action=start
结果是:
200 OK
响应不包含任何数据。
但是工作流程的工作没有开始。
然后我尝试启动
PUT {namenode}:11000/oozie/v1/job/0000001-150528075707705-oozie-oozi-W?action=rerun
结果是:
500 Internal Server Error
Apache Tomcat / 6.0.41 - 错误报告

注意 Apache Tomcat / 6.0.41日志中提供了根本原因的完整堆栈跟踪。
作业在HDFS和其余命令上:
GET {namenode}:11000/oozie/v1/job/0000001-150528075707705-oozie-oozi-W?show=info
工作正常。答案是:
200 OK

使用API Rest重新运行Oozie中与工作流程相关的工作的最简单方法是什么? 根据官方文档中的建议,这项工作不起作用:

PUT对于重播似乎是正确的。但是,它还需要为两个属性之一提供XML
<?xml version="1.0" encoding="UTF-8"?><configuration><property> <name>oozie.wf.rerun.failnodes</name> <value>false</value> </property></configuration>
或
<?xml version="1.0" encoding="UTF-8"?><configuration><property> <name>oozie.wf.rerun.skip.nodes</name> <value>,</value> </property></configuration>
确定重新运行或跳过哪些节点。
