Hi user@ambari, I am trying to use Ambari 1.6.1 to install HDP 2.1 on a two-machine cluster (EC2 r3.large instances, SUSE Linux Enterprise Server 11 sp3). I have successfully installed and started the Ambari server, and in the web UI's "Confirm Hosts" step, the installation failed.
Here's the log for one of the hosts: http://pastebin.com/6JMMbaDL Doing a "ps aux | grep zypper" on that host gives: ip-172-31-18-208:~ # ps aux | grep zypper root 19622 0.0 0.0 11584 1452 pts/1 S+ 01:41 0:00 bash -c zypper -q search -s --match-exact ambari-agent | grep ambari-agent | sed -re 's/\s+/ /g' | cut -d '|' -f 4 | tr '\n' ', ' | sed -s 's/[-|~][A-Za-z0-9]*//g' root 19623 0.5 0.0 113112 12208 pts/1 S+ 01:41 0:00 zypper -q search -s --match-exact ambari-agent root 20135 0.0 0.0 5716 820 pts/0 S+ 01:41 0:00 grep zypper The top two processes seem to be long-lived/stuck. And `zypper install ambari-agent` on that host gives: System management is locked by the application with pid 19623 (zypper). Close this application before trying again. I am wondering, what's the root cause here, and how can I resolve this issue? I am happy to provide more details if that's helpful for diagnosis. Cheers, Zongheng
