Cloudera ODBC connectivity issues with Impala

I have cloudera vm with cloudera version 5.7.0. I have secured Impala 2.5.0 using kerberos.I am able to connect to impala using impala-shell in kerberos mode using 'impala-shell -k'. But when i try to connect to impala from cloudera odbc connector  with the DNS configuration shown below,i'm getting this error when i try to test the first time:

[Cloudera][ImpalaODBC] (100) Error from the Impala Thrift API: SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure.  Minor code may provide more information (Permission denied)

 

impala_odbc.pngerror 1

 

When i try to test the connection for the same DNS configuration the second time I get this error:

[Cloudera][ImpalaODBC] (100) Error from the Impala Thrift API: SASL(0): successful result:

 

 

impala_odbc2.pngerror 2

 

How can I fix this?

 

Thanks,

what is your ODBC version? you need to make sure the impala version is compatible to ODBC
