nameNode=hdfs://hadoop:8020
jobTracker=hadoop:8032
queueName=default
oozieAppsRoot=user/root/oozie-apps
oozieDataRoot=user/root/oozie/datas

oozie.use.system.libpath=true

oozie.wf.application.path=${nameNode}/${oozieAppsRoot}/hive-select/

outputDir=hive-select/output

3.拷貝hive的配置文件hive-site.xm

4.拷貝mysql的jar包
