Hi,
I'm trying to install CDH 6.2 on a single node using Cloudera Manager. No matter what I do, I keep getting 'no heartbeat' error. I've checked firewall setting and open ports. I'm beginning to suspect it's because I'm using 'localhost' as my node name. I' use 'localhost' because Cloudera Manager tells me the actual node name is already being managed. Sure enough, I look at the mysql scm database, and there is a line in HOSTS table with the actual node name and IP address.
Is it possible to install CDH on a single node? Can you use 'localhost' as the node name? Something else I can try (hack database tables, /etc/host, ...)?
Thanks for any information!
