Ok, I understand this question has been asked many times but I would like a definitive answer on this as there are are many conflicting answers. I keep having issues with my Ambari UI. I am using hortonworks 2.5 Virtual Machine. Heres the problem, when I load the fresh VM first time, ambari UI loads fine and I can use its services. When I shut it down, I tried as suggested, I 'Stop-All' services in ambari UI, and paused and saved the VM before closing it, as many suggested.
Then....when I come back the next day (use it the 2nd time) the problem starts... I turn on HDFS, YARN in that order, but the services cant start, with an orange bar, instead of green, that its in progress, and then it cant be opened. It stays like this many hours or never.
So I would like to ask, WHAT IS THE PROBLEM?? Is it with my computer, or is there another way to shut down VM that I am not following? Am i missing something fundamental here?? I am at the edge of my wits, Been at it for 4-5 days spending 10 hours each day and I cant figure it out. Please Help.
I didn't follow your other thread usually when you run the "Stop all" all the services should shutdown correctly and then you just shut down the VM, I don't understand why you paused the VM?
Have you Enabled virtualization extensions in your BIOS? If you aint sure check it out!
My problem is, my sandbox was working, I was doing a few pig tutorials via ambari the first couple of hours, when I come back on the next day, nothing loads in the ambari UI, like heartbeat lost. If it was a virtualisation problem it wouldnt have worked in the first place, right?
Sometimes pausing VM causes some N/W services interruption. So please try shutting down the VM and then try restarting the VM once. In most cases it should fix the issue.
However If you still face any issue even after restarting the VM then please try restarting the ambari agent and share the complete agent log.
# ambari-agent restart ; tail -f /var/log/ambari-agent/ambari-agent.log
So I press exit on virtual machine, then when it prompts me with this screen i choose option 'send the shutdown signal' correct?
