复制样例重新命名后对hive进行修改

 cp -r  examples/apps/hive oozie-apps/
mv oozie-apps/hive  hive-select

修改hive-select中的job.properties

nameNode=hdfs://hadoop-senior.beifeng.com:8020
jobTracker=hadoop-senior.beifeng.com:8032
queueName=default
examplesRoot=examples
oozieAppsRoot=user/beifeng/oozie-apps
oozieDataRoot=user/beifeng/oozie/datas

oozie.use.system.libpath=true
oozie.wf.application.path=${nameNode}/${oozieAppsRoot}/hive-select/workflow.xml

inputDir=hive-select/input
outputDir=hive-select/output

oozie.use.system.libpath=true 表示使用hdfs系统beifeng用户下的share依赖包。
注意：端口号是否正确。hdfs：8020 jobtracker：8032

测试hive使用的api是新版本还是老版本

• [beifeng@hadoop-senior hive-0.13.1-cdh5.3.6]$ bin/hive
• select count(1) from dept;
• http://hadoop-senior.beifeng.com:8088/cluster
  
  

在hive中创建dept表

CREATE TABLE IF NOT EXISTS default.dept
(
dept_no string COMMENT 'id',
dept_name string ,
dept_url string 
)
COMMENT 'dept'
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t'
STORED AS TEXTFILE
LOCATION '/user/hive/warehouse/dept'

编写hive的sql脚本

load data local inpath '/opt/datas/dept.txt' overwrite into table dept;

编写流程xml文件

注意：workflow和hive的版本信息。根据.cloudera的oozie官方文档说明为主。

创建hdfs上的oozie-app目录

bin/hdfs dfs -mkdir -p  /user/beifeng/oozie-apps

复制oozie中的工作流select-dept到hdfs系统

../hadoop-2.5.0-cdh5.3.6/bin/hdfs dfs -put oozie-apps/hive-select /user/beifeng/oozie-apps/

复制hive配置文件及修改工作流文件

cp ../hive-0.13.1-cdh5.3.6/conf/hive-site.xml oozie-apps/hive-select/

创建hive的依赖jar包lib及上传

mkdir -p oozie-apps/hive-select/lib
cp ../hive-0.13.1-cdh5.3.6/lib/mysql-connector-java-5.1.27-bin.jar oozie-apps/hive-select/lib

复制hive-select 到HDFS

bin/hdfs dfs -put ../oozie-4.0.0-cdh5.3.6/oozie-apps/hive-select/* /user/beifeng/oozie-apps/hive-select/

设置oozie请求地址

export OOZIE_URL=http://hadoop-senior.beifeng.com:11000/oozie

运行job

bin/oozie job -config oozie-apps/hive-select/job.properties -run

查看job运行状态

bin/oozie job -info 0000001-180315133250705-oozie-beif-W

查看mysql中dept表中是否已有数据
