----------------------------------------------
ODBC INSTALLATION
Follow Below Steps :
1. Install hiveodbc client in cluster
2. create directory /opt/odbc and download
hiveODBC client into /opt/odbc
3. run the following command
rpm -ivh <hiveodbc_client> --nodeps --force
4. Install unixODBC server in cluster
5. Download unixODBC-origin-2.3.6.tar.gz into /opt/odbc
6. Compile unixODBC
./configure --enable-gui=no --enable-readline=no -prefix=/opt/odbc /unixODBC-2.3.6/unixodbc
make && make install
7. Configure respective odbc.ini file
[spark2xsingle]
DRIVER=/usr/lib64/libodbchive.so
MODE=0
HOST=xxxx( Thriftserver IP)
PORT=xxxxxxxx( Thriftserver Port)
DATABASE=default
[PRINCIPAL=spark/hadoop@HADOOP.COM|mailto:PRINCIPAL=spark/hadoop@HADOOP.COM]
FRAMED=0
NAMESPACE=sparkthriftserver2x
8.Add the odbc jars to the classPath
9.Run the following command to launch hive client
isql –v spark2xsingle
