python 与 hiveserver2 连接时 Hive Server 2 错误

Question

我正在使用

Centos，Python2.7，配置单元 2.1，Hadoop 2.7.2，pyHive

这是代码

from pyhive import hive
from TCLIService.ttypes import TOperationState
cursor = hive.connect('localhost').cursor()
cursor.execute('SELECT * FROM my_awesome_data LIMIT 10', async=True)

#status = cursor.poll().operationState
#while status in (TOperationState.INITIALIZED_STATE, TOperationState.RUNNI$
#    logs = cursor.fetch_logs()
#    for message in logs:
#        print message

# If needed, an asynchronous query can be cancelled at any time with:
# cursor.cancel()

# status = cursor.poll().operationState

#print cursor.fetchall()

当我运行 python /usr/local/py/test5.py 在终端显示....

Traceback (most recent call last):
File "/usr/local/py/test5.py", line 3, in <module>
cursor = hive.connect('localhost').cursor()
File "/usr/local/lib/python2.7/site-packages/pyhive/hive.py", line 63, in connect
return Connection(*args, **kwargs)

status, payload = self._recv_sasl_message()
File "/usr/local/lib/python2.7/site-packages/thrift_sasl/__init__.py", line 98, in _recv_sasl_message
header = read_all_compat(self._trans, 5)
File "/usr/local/lib/python2.7/site-packages/thrift_sasl/six.py", line 31, in <lambda>
read_all_compat = lambda trans, sz: trans.readAll(sz)
File "/usr/local/lib/python2.7/site-packages/thrift/transport/TTransport.py", line 58, in readAll
chunk = self.read(sz - have)
File "/usr/local/lib/python2.7/site-packages/thrift/transport/TSocket.py", line 120, in read
message='TSocket read 0 bytes')
thrift.transport.TTransport.TTransportException: TSocket read 0 bytes

在此之后显示的 Hive 服务器错误日志...

ERROR [HiveServer2-Handler-Pool: Thread-41]: server.TThreadPoolServer (:()) - Thrift error occur$
org.apache.thrift.protocol.TProtocolException: Missing version in readMessageBegin, old client?

我也试过 pyhs2 得到同样的错误

出了什么问题？

谢谢

Answer 1

我已经用这些版本解决了这个错误：

Centos 7、Python2.7、配置单元 2.1、Hadoop 2.7.3 和 java java 1.7.0_91

使用impyla

它对我有用。

Answer 2

thrift.transport.TTransport.TTransportException: TSocket read 0 bytes

我遇到了同样的问题并通过
