Reference: "Use Hadoop Cluster" option in Data Import/Export

Data Import and Data Export have the option to use a specific Hadoop Cluster by checking the "Use Hadoop Cluster" option and selecting a cluster from the drop-down of available clusters.

When "Use Hadoop Cluster" is left unchecked Qubole will use its internal cluster and data will flow through Qubole.

If a Hadoop Cluster is selected, you must make sure that the data is accessible by the cluster.  For example, if the data is in Redshift, the Redshift Database Server must be accessible to the Cluster's Security Group from the VPC/Subnet that the cluster is running.
