Hello! I bealive I have similar (or identical) problem but I don't fully understand explanation. I'm installing cluster on two virtual machines with Ubuntu 12.04 on them. Both have two network interfaces eth0 and eth1. eth0 is connection with internet through NAT and eth1 is virtual network between them.  Host 1 name is Hadoop1.local and its IP (eth1) is: 192.168.56.101. Host 2 name is Hadoop2.local and its IP (eth1) is: 192.168.56.102   I start Cloudera Manager instalator on Hadoop1. In step "" I type both IP addresses (.101 & .102) (Is it OK or should I only start installation on second host- Hadoop2). During "Cluster Installation" step on Hadoop1 I get error: "Installation failed. Failed to receive heart beat from agent". I check ports 7182, 9000, 9001 and those are OK (before I start installation those are empty, after installation I have python on them). In /var/log/cloudera-scm-agent I see no errors.   So I assume there is something wrong with my hosts names.   My /etc/host looks like this (Hadoop1):   127.0.0.1 localhost loopback 192.168.56.102 Hadoop2.local   And second /etc/host like this (Hadoop2):   127.0.0.1 localhost loopback 192.168.56.101 Hadoop1.local   Any help would be appreciate!

Hello! Thanks for answering. Unfortunately in /tmp there is no files You said. There is only catalog: /tmp/hsperfdata_cloudera-scm and in this catalog is one file: 1422. This is binary file so I am not sure You want to watch on it. On the second node there is no files or catalogs in /tmp that might by conected with CDH. Any idea what to do next?   Regards Andrzej ...
