I am new to Dremio and I just installed the lastest Dremio and JAVA 1.8.0_172 on my Windows 10 64-bit computer. However when I click “start” in the GUI, it changes to “Dremio is starting up” for a minute and back to “Dremio is not running”. I have been stuck here for a day… Any help will be appreciated!
Hi @Xiao_Marshall_Ma Under program files - dremio - conf there should be a file called logback.xml. Can you please take a backup of the file first then edit the original file, look for the below entry and change error to debug? try to start Dremio again and send us the server.log?
Thanks @Xiao_Marshall_Ma, I will go through the DEBUG logs and get back to you. Meanwhile you can put back error instead of debug or move back the original file as logback.xml
@balaji.ramaswamy asked that you turn on some verbose logging. Can you turn on some additional logging in order diagnose this better? Under Program Files\Dremio\conf in the same logback.xml file he pointed you to, can you make a backup and then change the info in:
Thanks for reaching out! I am not sure how to change that but I think my logback.xml already has the code you want me to change. Here’s the complete content of my current logback.xml:
go to “Programs and Features” via Start menu, and uninstall Dremio.
go to “C:\Users<username>\AppData\Local” folder in File Explorer, where is user name. Delete “Dremio” folder. “AppData” is a hidden folder, so you have to make it visible.
reinstall Dremio, and wait for 2 minutes before stopping Dremio.
Hi,
I am facing the same issue now. I tried following the ‘uninstall…and then re-install’ workaround. But it keeps throwing the same error as above.
Dremio is exiting. Failure while starting services.
