python自动生成执行集群操作脚本

外部转入参数，循环列表生成脚本，并执行：

#!/usr/bin/python#import sysimport oslist=['2016-06-07','2016-06-08','2016-06-09','2016-06-10','2016-06-11','2016-06-12','2016-06-13']for d in list:    cmd='hadoop distcp hftp://hadoop2:50070/user/datamart/adobe/adobe.'+sys.argv[1]+'/'+d+' /user/hive/warehouse/adobe.db/'+sys.argv[2]+'/load_day='+d    print cmd    os.system(cmd)for d in list:    cmd='hive -e"alter table adobe.'+sys.argv[2]+' add partition(load_day=\''+d+'\') location \'/user/hive/warehouse/adobe.db/'+sys.argv[2]+'/load_day='+d+'\';"'    print cmd    os.system(cmd)print 'ok'

后台执行脚本：

nohup python distcpData.py ADOBE_NWD_PRD adobe_nwd_prd > prd.log &
