本文介绍了一个使用Apache Oozie实现的复杂工作流案例，包括Hive表创建、Shell脚本执行日期获取、Sqoop数据导入及Hive分区表更新等步骤。此流程展示了如何通过Oozie协调多种Hadoop生态系统组件来完成日常的数据处理任务。

示例

create.q

create external table IF NOT EXISTS default.SYS_ACCOUNT
(
  account_id           double,
  account_name         string,
  account_password     string,
  status               int,
  last_login_device_id string,
  band_device_id       string,
  key                  string,
  last_login_ip        string,
  account_type         int,
  lock_time            DATE,
  account_password_ver string
)
partitioned by (date_time string) 
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\001'
location '/data/hive/sys_account';

job.properties

nameNode=hdfs://fuze250:8020
jobTracker=fuze250:8032
#nameNode=hdfs://nameservice
#jobTracker=yarnRM
queueName=default
oozieRoot=oozie
hiveRoot=hive

oozie.use.system.libpath=true
oozie.libpath=/user/oozie/share/lib
oozie.wf.application.path=${nameNode}/user/${user.name}/${oozieRoot}/sqoop/sys_account_user_vip

procedure.q

ALTER TABLE default.SYS_ACCOUNT ADD PARTITION (date_time=${date_time}) location '/data/hive/sys_account/date_time=${date_time}';

script.sh

#!/bin/bash
DATE=$(date +%Y%m%d);
echo date_time=$DATE
