TypeError('__str__ returned non-string (type bytes)',)

Hi,

I'm using happybase==1.0.0 & thriftpy==0.3.9 to scan a table,
at very uncertain point(different each time), it throws exception like below, can anyone give me some hint on what happened?

/python3.5/site-packages/happybase/table.py in scan(self, row_start, row_stop, row_prefix, columns, filter, timestamp, include_timestamp, batch_size, scan_batching, limit, sorted_columns)
    393                 items = self.connection.client.scannerGetList(
--> 394                     scan_id, how_many)
    395

/python3.5/site-packages/thriftpy/thrift.py in _req(self, _api, *args, **kwargs)
    197         if not getattr(result_cls, "oneway"):
--> 198             return self._recv(_api)
    199

/python3.5/site-packages/thriftpy/thrift.py in _recv(self, _api)
    214             self._iprot.read_message_end()
--> 215             raise x
    216         result = getattr(self._service, _api + "_result")()

<class 'str'>: (<class 'TypeError'>, TypeError('__str__ returned non-string (type bytes)',))

Any update on this one ?

It means that the thrift server received messages as bytes, which is linked to using Thrift version 2 according to this SO Post

Happybase only supports Thrift version 1 protocol at the moment according to thheir doc
The solution to me was to restart the server with hbase thrift1 start and it fixed it.
