cloudbreak 2.7.1 crashing

Current issue I'm having: * Cloudbreak deployment server stops serving the web UI and becomes unusable after 30-90 minutes of use. * Restarting cbd ("cbd restart") at the shell prompt may bring the GUI back up some of the time, but the username/password doesn't work, and when I use linux to reset the passwd, I can login to the GUI, but it has lost all of my configurations and clusters and gives an error indicating that the UI cannot connect to CloudBreak. * I have now scrapped it and started over 3 times (generating 3 new CloudBreak deployment VMs) and had the same result every time. More details and background: I downloaded and installed CloudBreak 2.7.1 for Centos7. I used it to generate a cbd-deployment virtual machine (in GCP), following the QuickStart (https://docs.hortonworks.com/HDPDocuments/Cloudbreak/Cloudbreak-2.7.1/content/gcp-quick/index.html#gcp-apis). It successfully ran and spit out a new public IP address for me to log into via https://THE_IP_ADDRESS. I navigated into the Cloudbreak GUI and logged in with my admin user auth. I went through the enitre process of setting up certs and deploying a cluster according to one of the blueprints. Everything worked wonderfully!! So excited! Then, a half hour later when I tried using the cloudbreak deployment gui again, the server was no longer responding. I used ssh to connect into the linux shell and see what was going on. I found a couple of topics here in the HCC forum, that gave hints for troubleshooting the issue. Here are the two that seemed promising: https://community.hortonworks.com/questions/190952/cloudbreak-ui-is-not-accessible-after-restart-vm.html https://community.hortonworks.com/questions/191337/cloudbreak-ui-is-not-able-to-connect-cloudbreak.html I tried a few things from the first article: cd /var/lib/cloudbreak-deployment cbd ps cbd start This didn't solve the problem. Reading further, I tried: cbd restart This enabled the GUI again, but bad user/passwd auth. I used the linux "passwd" command to reset the password for my admin user, and once again I could get past the login screen. But, as noted above, an error popped up stating that it could not connect to CloudBreak. A red-badge at the upper-right side of the GUI highlighted [CloudBreak 0] as being in a failed state. All of the GUI screens (clusters, blueprints, credentials) showed up blank (no data). All is lost!!! 😉 Not knowing what else to do, I started over. I have checked that SELinux and firewalld are disabled on the VM that cloudbreak generated for me. Initially, SELinux is disabled but firewalld was active (in the generated vm). So, I disabled and stopped the firewalld service and tried to "cbd restart". Now (on my 3rd dead cloudbreak-deploy vm box), I can't seem to revive even the GUI to the point where it will let me login. Is the deployment vm generated by Cloudbreak 2.7.1 this unstable for everyone? Is Centos7 a bad mix with this version? Any suggestions please! I would love to use Cloudbreak, but I'm losing a little confidence in it's ability to not lose all my data and crash. Lol. Thanks in advance! -Phil ... View more
