Connecting
To connect to HDFS, you can use either a DSN or an ODBC connection string. Both of these methods use the odbc_connect function.
Connect to a DSN
To connect using a DSN:
$cnx = odbc_connect("CData HDFS Sys", "", "");
Provide a Driver Connection String
To connect using an ODBC connection string:
$cnx = odbc_connect("DRIVER={CData ODBC Driver for HDFS};Host=sandbox-hdp.hortonworks.com;Port=50070;Path=/user/root;", "", "");
