Yet that page simply says that "IPv6 is not supported and must be disabled."
If this is a hard requirement, then why is there no documentation on *how* to disable IPv6 for the various supported OSs? I understand that Cloudera may not want to get into the OS configuration business, but at least pointers to vender documentation should be provided.
