Workflow-Shell Action

本workflow位于oozie目录下新创建的一个oozie-apps文件夹下的shell文件夹中。

作用为：用hive执行 hive -f user.sql  语句

shell：

1、job.properties

2、test.sh         (shell脚本)

3、user.sql       (hive的一个查询语句)

3、workflow.xml

将整个oozie-apps文件夹上传到hdfs的对应用户目录下

然后运行程序

bin/oozie job -config oozie-apps/shell/job.properties -run

user.sql

insert overwrite directory '/user/bpf/ozzie/datas/shell/output'
select * from default.user

test.sh

#!/bin/bash
/opt/cdh-5.5.0/hive-1.1.0-cdh5.5.0/bin/hive -f user.sql

job.properties

nameNode=hdfs://BPF:9000
jobTracker=BPF:8032
queueName=default
oozieappsRoot=user/bpf/oozie-apps
DataRoot=user/bpf/oozie/datas
EXEC=test.sh
script=user.sql

oozie.wf.application.path=${nameNode}/${oozieappsRoot}/shell/workflow.xml
