任务流之间的调度依赖

检查任务

jobA

java 复制代码

#!/bin/bash
echo "do JobA"



r=`java -cp ./scheduler-1.0-SNAPSHOT-jar-with-dependencies.jar com.mz.scheduler.FlowCheck common_process`



echo 'result is:'$r

echo ${r} >> "${JOB_OUTPUT_PROP_FILE}"

jobB

新的flow开启的第一个job

java 复制代码

#!/bin/bash
echo "do JobB"

定义flow

jobA和jobB任务依赖文件

java 复制代码

nodes:
  - name: jobA
    type: command
    config:
      command: sh jobA.sh


  - name: jobB
    type: command
    dependsOn:
      - jobA
    config:
      command: sh jobB.sh
    condition: ${jobA:ok} == "true"

打包

这种情况下的打包需要将jar包一同打入zip

因为JobA引用了java处理的逻辑
