> In the ODBC driver - 
> The krbSpnConfigurationsRequired parameter in odbc.ini is not working as expected.  If
I set the following:
> AuthenticationType=Kerberos
> UID=
> PWD=
> DelegationUID=
> KrbServiceName=
> KrbServiceHost=maprsasl
> krbSpnConfigurationsRequired=1
> I could connect successfully.  I was expecting to get an error message.  If only either
KrbServiceHost is missing or both KrbServiceHost and KrbServiceName are missing then I get
the expected error message.
> Turning off the parameter, I was able to connect using the following setting:
> AuthenticationType=Kerberos
> UID=
> PWD=
> DelegationUID=
> KrbServiceName=
> KrbServiceHost=maprsasl
> krbSpnConfigurationsRequired=0
> However, if either KrbServiceHost or both KrbServiceHost and KrbServiceName are missing,
I would get the following error message:
> 1: SQLDriverConnect = [MapR][Drill] (30)  User authentication failed. Server message:
DrillClientImpl::handleAuthentication: Authentication failed. [Details:  Encryption: enabled
,MaxWrappedSize: 32768 ,WrapSizeLimit: 0, Error: -1]. Check connection parameters? (30) SQLSTATE=28000
> 1: ODBC_Connect = [MapR][Drill] (30)  User authentication failed. Server message: DrillClientImpl::handleAuthentication:
Authentication failed. [Details:  Encryption: enabled ,MaxWrappedSize: 32768 ,WrapSizeLimit:
0, Error: -1]. Check connection parameters? (30) SQLSTATE=28000
> The Drill C++ Client should set service_host to the connected host (if direct) if service_host
is empty (similar logic for zookeeper connection). Going through the source code, looks like
this logic was removed by this commit: https://github.com/apache/drill/commit/f246c3cad7f44baeb8153913052ebc963c62276a#diff-8e6df071d8ca863fcfa578892944c1dcL123
