Description

$ impala-shell -i xxxxxxxxxxx.vpc.cloudera.com -d default -k --ssl --ca_cert /xxxxxx.pem
Starting Impala Shell with Kerberos authentication using Python 2.7.5
Using service name 'impala'
SSL is enabled
No handlers could be found for logger "thrift.transport.sslcompat"
Error connecting: NotImplementedError, Wrong number of arguments for overloaded function 'Client_setAttr'.
  Possible C/C++ prototypes are:
    setAttr(saslwrapper::Client *,std::string const &,std::string const &)
    setAttr(saslwrapper::Client *,std::string const &,uint32_t)

This was caused by the unicode changes in "IMPALA-3343, IMPALA-9489: Make impala-shell compatible with python 3" - in some places a unicode string gets passed into the sasl library, and the older version of the library can't handle it. The SASL upgrade - IMPALA-9719 - fixes it.
