Hi,   I am trying to connect to impala using ODBC from Ubuntu x64 14.04 machine using iodbc 3.52.7. I copied the /opt/cloudera/impalaodbc/Setup/odbc.ini to /var/tmp/odbc.ini & edited:   HOST=localhost PORT=21050   to the [Sample Cloudera Impala DSN 64].   $ ODBCINI=/var/tmp/odbc.ini   ./iodbctest Enter ODBC connect string (? shows list): Sample Cloudera Impala DSN 64 1: SQLDriverConnect = [Cloudera][ODBC] (10360) Invalid connection string. (10360) SQLSTATE=HY000 1: ODBC_Connect = [Cloudera][ODBC] (10360) Invalid connection string. (10360) SQLSTATE=HY000   === log from SimbaImpalaODBC_driver.log == Dec 07 18:10:50 DEBUG 1149306688 DSProductHelper::LogProductInfo: Vendor name: Cloudera Dec 07 18:10:50 DEBUG 1149306688 DSProductHelper::LogProductInfo: Driver name: Cloudera ODBC Driver for Impala Dec 07 18:10:50 DEBUG 1149306688 DSProductHelper::LogProductInfo: Driver version: 2.5.30.1011 Dec 07 18:10:50 DEBUG 1149306688 DSProductHelper::LogProductInfo: Unknown loaded this 64-bit driver Dec 07 18:10:50 INFO  1149306688 Driver::LogVersions: SDK Version: 09.03.10.1011 Dec 07 18:10:50 INFO  1149306688 Driver::LogVersions: DSII Version: 2.5.30.1011 Dec 07 18:10:50 INFO  1149306688 Driver::Initialize: Database CHAR Encoding: UTF-8 Dec 07 18:10:50 INFO  1149306688 Driver::Initialize: Database WCHAR Encoding: UTF-16LE Dec 07 18:10:50 INFO  1149306688 Driver::Initialize: ANSI CHAR Encoding: UTF-8 Dec 07 18:10:50 INFO  1149306688 Driver::Initialize: Driver Manager WCHAR Encoding: UTF-32LE Dec 07 18:10:50 INFO  1149306688 Driver::Initialize: Locale name: en_US Dec 07 18:10:50 INFO  1149306688 Driver::Initialize: Bitness: 64-bit Dec 07 18:10:50 TRACE 1149306688 CInterface::SQLAllocHandle: +++++ enter +++++ Dec 07 18:10:50 INFO  1149306688 CInterface::SQLAllocHandle: Allocating environment handle.
