PyHive : thrift.transport.TTransport.TTransportException: 'Error in sasl_decode (-1) SASL(-1): generic failure: Unable to find a callback: 32775'

PyHive : thrift.transport.TTransport.TTransportException: 'Error in sasl_decode (-1) SASL(-1): generic failure: Unable to find a callback: 32775'

I've create a Python script for connect to Hiveserver2 to perform queries databases.

My code are working fine, it's running for a while until the error came out.

 

 

thrift.transport.TTransport.TTransportException: 'Error in sasl_decode (-1) SASL(-1): generic failure: Unable to find a callback: 32775'

 

 

From investigated, I guess it might be something about Thrift SASL library 

https://github.com/cloudera/thrift_sasl/blob/master/thrift_sasl/__init__.py

 

 

  def _read_frame(self):
    header = self._trans.read(4)
    (length,) = struct.unpack(">I", header)
    if self.encode:
      # If the frames are encoded (i.e. you're using a QOP of auth-int or
      # auth-conf), then make sure to include the header in the bytes you send to
      # sasl.decode()
      encoded = header + self._trans.read(length)
      success, decoded = self.sasl.decode(encoded)
      if not success:
        raise TTransportException(type=TTransportException.UNKNOWN,
                                  message=self.sasl.getError())

 

 

I have no idea what's cause the exception occurred. Any suggestion would be nice!

How to fix this problem ?

Thanks

This error usually happens if the client doesnt match the QOP on server.

 

Can you share the connection string used in your code snippet? Is your hiveserver2 kerberised? Can you please share what is the value set for this property hive.server2.thrift.sasl.qop in your hiveserver2's hive-site.xml?

 

Example connection string is in link https://github.com/dropbox/PyHive/pull/135/files/ec5270c4b6556bcd20f0f81afbced4a69ca9eff0
