in python 3 environment when kerberos_host_fqdn option is used
In Pyhton 2, the sasl layer does not accept unicode strings,
so we have to explicitly encode the kerberos_host_fqdn string
to ascii. However, this is not the case in python 3, where
we have to omit the encode, because if we don't do this,
impala-shell wants to use the following service principal
during Kerberos auth:
my_service_name/b'my.kerberos.host.fqdn'@MY.REALM
instead of the correct one, which is:
my_service_name/my.kerberos.host.fqdn@MY.REALM
(This is because the output of the encode function
is a byte array in python 3.)
Tested with new unit tests and with a snapshot build
manually in CDP PVC DS.
