I'm trying to get a table located in hive (hortonworks) ,to collect some twitter data to implement on a machine learning project, using pyhive since pyhs2 is not supported by python3.6.
Here's my code:
from pyhive import hive
conn = hive.Connection(host='192.168.1.11', port=10000, auth='NOSASL')
import pandas as pd
import sys
df = pd.read_sql("SELECT * FROM my_table", conn)
print(sys.getsizeof(df))
df.head()When compiling I get this error:
Traceback (most recent call last): File "C:\Users\PWST112\Desktop\import.py", line 44, in <module> conn = hive.Connection(host='192.168.1.11', port=10000, auth='NOSASL') File "C:\Users\PWST112\AppData\Local\Programs\Python\Python36\lib\site- packages\pyhive\hive.py", line 164, in __init__ response = self._client.OpenSession(open_session_req) File "C:\Users\PWST112\AppData\Local\Programs\Python\Python36\lib\site- packages\TCLIService\TCLIService.py", line 187, in OpenSession return self.recv_OpenSession() File "C:\Users\PWST112\AppData\Local\Programs\Python\Python36\lib\site-packages\TCLIService\TCLIService.py", line 199, in recv_OpenSession (fname, mtype, rseqid) = iprot.readMessageBegin() File "C:\Users\PWST112\AppData\Local\Programs\Python\Python36\lib\site-packages\thrift\protocol\TBinaryProtocol.py", line 148, in readMessageBegin name = self.trans.readAll(sz) File "C:\Users\PWST112\AppData\Local\Programs\Python\Python36\lib\site-packages\thrift\transport\TTransport.py", line 60, in readAll chunk = self.read(sz - have) File "C:\Users\PWST112\AppData\Local\Programs\Python\Python36\lib\site-packages\thrift\transport\TTransport.py", line 161, in read self.__rbuf = BufferIO(self.__trans.read(max(sz, self.__rbuf_size))) File "C:\Users\PWST112\AppData\Local\Programs\Python\Python36\lib\site-packages\thrift\transport\TSocket.py", line 132, in read message='TSocket read 0 bytes') thrift.transport.TTransport.TTransportException: TSocket read 0 bytes [Finished in 0.3s]

I have my sandbox configured for "NONE" authentication, since the NOSASL option is not available.

I had a similar problem with pyhive on my horton setup. The failure was always immediate and so it was not a timeout issue that some people on the net were pointing out.
It turned out to be hive.server2.transport.mode. If this is set to binary, it works like a Charm. If it is 'http', PyHive does not work.
Also found https://github.com/dropbox/PyHive/issues/69 which talks about this. HTH.
