To connect to HDFS, you can use either a DSN or an ODBC connection string. Both of these methods use the odbcConnect function.

Connect to a DSN

To connect using a DSN:

cnx <- odbcConnect("CData HDFS Sys")

Provide a Driver Connection String

To connect using an ODBC connection string:

cnx <- odbcDriverConnect(connection = "DRIVER={CData ODBC Driver for HDFS};Host=sandbox-hdp.hortonworks.com;Port=50070;Path=/user/root;")
