from pyspark import SparkContext,SparkConf,HiveContext
conf = SparkConf()
sc = SparkContext(conf=conf)
df_tmp = list_filter_websiteids.where('WebsiteID in ({})'.format(','.join(['1','71']))).filter(list_filter_websiteids['IsDeleted']==True)
# 过滤生成dataframe
df_tmp.registerTempTable('test_hive') # 将dataframe 注册临时表
hivec = HiveContext(sc) # 生成HiveContext对象
hivec.sql('create table test.product select * from test_hive') # 将临时表的数据，写入到hive表
