I have Cloudera Hadoop running with no issues. All I have are 32-bit Oracle Linux environments. It appears I need a 64-bit Oracle environment to install the connector because it has to have Hadoop installed atop of it.
It there a 64-bit Oracle Linux virtual box or VM appliance for a Windows 7 64 host that I can use for testing? Even better, one that has the HADOOP connector and SQL Loader already installed?
We are planning a VM that will have 64 bit Linux with single node Hadoop, connectors and a database. I will post a note when it is available.
Meanwhile, it is straightforward to have a 64 bit Oracle Database install and then add the Hadoop client that one of the connectors needs. The connectors documentation points to instructions for installing the Hadoop client.
