I am able to connect to hive using Clouder's odbc driver for Hive now. Now I am configuring Cloudera Impala ODBC driver on the same database server, when I test the connection, I ran into the following error, what does this indicate? $ isql -v impldsn [S1000][unixODBC][Cloudera][ODBC] (11560) Unable to locate SQLGetPrivateProfileString function. [ISQL]ERROR: Could not SQLConnect What does it indicate? Linda Here is my IMPLDSN in my ODBC.ini file: [IMPLDSN] # Description: DSN Description. # This key is not necessary and is only to give a description of the data source. Description=Cloudera ODBC Driver for Impala (64-bit) DSN # Driver: The location where the ODBC driver is installed to. Driver=/opt/cloudera/impalaodbc/lib/64/libclouderaimpalaodbc64.so # The DriverUnicodeEncoding setting is only used for SimbaDM # When set to 1, SimbaDM runs in UTF-16 mode. # When set to 2, SimbaDM runs in UTF-8 mode. #DriverUnicodeEncoding=2 # Values for HOST, PORT, KrbFQDN, and KrbServiceName should be set here. # They can also be specified on the connection string.

I am working on a ‘approve of concept’ project to see how we can query/transfer data between oracle and our corporate data lake. I installed Cloudera ODBC Hive and Impala drivers, when I tried to test 'isql'onnections, it failed with the following error: [S1000][unixODBC][Cloudera][Hardy] (34) Error from server: connect() failed: Connection refused. [ISQL]ERROR: Could not SQLConnect Here is the detailed steps I followed, any input would be appreicated. Linda Environment: RedHat Linux 6.9 with UnixODBC in place Oracle DB: 12.1.02 with SID Name: lvdma01 wiht hivetest schema name created Downloaded and installed CouderaHiveODBC-2.5.19.1004-1.el6.x86_64.rpm as root Downloaded and installed ClouderaImpalaODBC-2.5.33.1004-1.el6.x86_64.rpm Configure Cloudera Hive ODBC after installation: Cd /opt/cloudera/hiveodbc/Setup mkdir -p /usr/local/odbc cp /opt/cloudera/hiveodbc/Setup/odbc.ini /opt/home/oracle/ --Note: oracle home dir is /opt/home/oracle cp /opt/cloudera/hiveodbc/lib/64/cloudera.hiveodbc.ini /etc/ Set cloudera environment variable: export ORACLE_SID=lvdma01 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=/u01/app/oracle/product/12.1.0.2 export ODBCINI=~/odbc.ini export ODBCSYSINI=/usr/local/odbc export CLOUDERAHIVEINI=/etc/cloudera.hiveodbc.ini export LD_LIBRARY_PATH=$ORACLE_HOME/lib export PATH=/usr/bin:/usr/ucb:/usr/sbin:/etc:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:/bin:/usr/ccs/bin:/usr/local/bin:.
