Error occurred during Kerberos library operation: Preauthentication failed - Impala ODBC Connection

[ Edited ]

Hi,

I am using Hive/Impala ODBC Connection. I am able to connect with Hive ODBC and not with Impala ODBC

 

I am getting the following error.

 

[unixODBC][Cloudera][KerberosSupport] Error occurred during Kerberos library operation: Preauthentication failed (SQL-HY000)

 

DBI connect('dsnname',username,...) failed: [unixODBC][Cloudera][ThriftExtension] (2) Error occured during authentication. (SQL-28000) .

 

[unixODBC][Cloudera][ThriftExtension] (6) Error occurred while contacting server: SSL_connect: error code: 0. This could be because you are trying to establish a SSL connection to a server that does not have SSL enabled. (SQL-HY000)

 

What are the parameters i need to check in odbc.ini file?

 

using same Kinit for Hive and Impala.

 

How to trouble shoot this issue?

 

 

Can anyone help? 

 

Thanks.
