------------------------------------
Summary: C++ Client should set service_host to the connected host
if service_host is empty
Key: DRILL-5968
URL: https://issues.apache.org/jira/browse/DRILL-5968
Project: Apache Drill
Issue Type: Bug
Reporter: Parth Chandra
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: ODBC_Connect = [MapR][Drill] (30) User authentication failed. Server

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:
