Solved it.   According to page 68 of the installation guide, you set the HttpPath parameter in your odbc.ini file, but that failed to work:   $ tail .odbc.ini # The client private key. This is used for two-way SSL authentication. ClientPrivateKey= # The password for the client private key. Password is only required for password protected # client private key. ClientPrivateKeyPassword= HttpPath=/cliservice $ isql -v ClouderaHiveDSN [S1000][unixODBC][Cloudera][Hardy] (34) Error from server: Bad Status: HTTP/1.1 404 Not Found. [ISQL]ERROR: Could not SQLConnect $ So I looked for path strings in the driver:   $ strings /opt/cloudera/hiveodbc/lib/64/libclouderahiveodbc64.so | grep -i path m_httpPath: %s m_trustedCertsPath: %s HttpPathPrefix ... I changed the paramter from HttpPath to HttpPathPrefix and was able to connect:   [novetta@cdh-1 ~]$ tail .odbc.ini # The client private key. This is used for two-way SSL authentication. ClientPrivateKey= # The password for the client private key. Password is only required for password protected # client private key. ClientPrivateKeyPassword= HttpPathPrefix=/cliservice [novetta@cdh-1 ~]$ isql -v ClouderaHiveDSN +---------------------------------------+ | Connected! | | | | sql-statement | | help [tablename] | | quit | | | +---------------------------------------+ SQL> Hope it helps! ...
