In Cognos, the metadata table/column names we get from Impala are all lower case

When we work in Cognos BI(working on converting our reports to Impala from BigSQL), the metadata table/column names we get from Impala are all lower case, but the same from BIGSQL are all uppercase case. Because of the case difference, we are not able to relink the data source in Cognos data module when we convert it from BIGSQL to Impala. This is creating a lot of manual efforts. Cognos cannot do the column mapping since Cognos is case sensitive. 
We need to have Impala metadata configured to have upper case, same as what we have for the bigsql.
We have attached the screen shots for the column name from the same table in bigsql vs impala.

We have reached out to Impala- Cloudera support and they asked to make below changes to the JDBC connection string, we made the changes as suggested but it didn't work, columns are still coming as lowercase from Impala. We had a session with Joe Prosser <jprosser@cloudera.com> from Cloudera but not able to find resolution so raised ticket with IBM. 

TS022576375 - This ticket has been raised, and discussion is in progress and it has been communicated that this feature will be considered for future release but we need this enhancement for our current version 12.0.4 as our migration project is in progress is currently under critical phase.

Connection string:-

jdbc:impala://nextgen-dev-impala.metlife.com:21050/default;AuthMech=1;KrbRealm=METNET.NET;KrbHostFQDN=nextgen-dev-impala.metlife.com;KrbServiceName=impala;KrbAuthType=2;SSL=1;UseNativeQuery=1;UpperCaseResultSetColumnName=true;LowerCaseResultSetColumnName=0
Below property has been suggested by Cloudera
In the Cognos JDBC connection configuration, try setting 

UseNativeQuery:
UpperCaseResultSetColName: 1
Also Make sure:
LowerCaseResultSetColumnName:0
