python上的Hive Server 2错误与hiveserver2连接

Question

I am using

Centos , Python2.7 , hive 2.1 ,Hadoop 2.7.2 ,pyHive

here is code

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()

when I run python /usr/local/py/test5.py in terminal its showing ....

Traceback (most recent call last):
File "/usr/local/py/test5.py", line 3, in <module>
cursor = hive.connect('localhost').cursor()

message='TSocket read 0 bytes')

Hive server error log showing after this...

Also I had tried pyhs2 getting same error

using impyla

its working for me.

Answer 2

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

I had the same problem and solved it by

1. Start hiveserver2 ( how to start hiveserver2 )
2. Modify your port. The default port is 10000 or you can change it to follow your hive_site.xml
