Yes. We had to enable SSL for impala. Final ODBC config like below [bigdata] Description=New Cloudera Cluster Driver=/opt/cloudera/impalaodbc/lib/64/libclouderaimpalaodbc64.so HOST=192.168.10.10 PORT=21050 Database=dbname AuthMech=4 UID=username PWD=password SSL=1 CAIssuedCertNamesMismatch=1 TrustedCerts=/opt/cloudera/impalaodbc/lib/64/your_impala_ssl_cert.pem KrbFQDN= KrbRealm= KrbServiceName= TSaslTransportBufSize=1000 RowsFetchedPerBlock=10000 SocketTimeout=0 StringColumnLength=32767 UseNativeQuery=0

LDAP is properly configured. We can coonect from impala-shell using LDAP username and passwords. SSL not enabled in Impala. I think due to overhead. Without LDAP (i.e. without authentication and AuthMech=0) this works properly. Configurations is as follows.

My ODBC driver (Linux 2.6.32-431.el6.x86_64 ODBC Driver version: 2.5.29.1009) worked properly without authentication. But after enabling the LDAP authentication for Impala I cannot connect. It gives following error. SSL not enabled in the Impala server. (JDBC seems work properly for some application) 1.
