Python如何连接和启动Hive

2 启动hive 的thrift

确保以下服务开启：

hive --service hiveserver

默认端口是10000

from hive_service import ThriftHive
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
def ReadHiveTest(sql):
try:
tSocket = TSocket.TSocket('172.18.1.88',10000)
tTransport = TTransport.TBufferedTransport(tSocket)
protocol = TBinaryProtocol.TBinaryProtocol(tTransport)
client = ThriftHive.Client(protocol)
tTransport.open()
client.execute(sql)
return client.fetchAll()
except Thrift.TException, tx:
print '%s' % (tx.message)
finally:
tTransport.close()
if __name__ == '__main__':
showDatabasesSql = 'show databases'
showTablesSql = 'show tables'
selectSql = 'SELECT * FROM 07_jn_mysql_2'
result = ReadHiveTest(selectSql)
print(result[1])
