Workflow-Shell Action

本workflow位於oozie目錄下新創建的一個oozie-apps文件夾下的shell文件夾中。

作用爲：用hive執行 hive -f user.sql  語句

shell：

1、job.properties

2、test.sh         (shell腳本)

3、user.sql       (hive的一個查詢語句)

3、workflow.xml

將整個oozie-apps文件夾上傳到hdfs的對應用戶目錄下

然後運行程序

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
