Hi puspitab, it took me sometime to figure out an easier solution. I tried Patricker’s option but went further by grepping all mentions of Narwhal in the dremio open source directory. Made all necessary changes but had compilation issues which I later fixed and compiled successfully.
I figured out an easier way however to resolve this and you will definitely need svg files for your company logo.
I renamed the company logo svg files using the dremio logo name files and just replaced the original dremio logo files with mine.
I updated /dac/ui/src/components/Icon/icons/Narwhal-Logo-With-Name-Light.svg
/dremio/dac/ui/src/components/Icon/icons/NarwhalLogo.svg
/dremio/dac/ui/src/components/Icon/icons/Narwhal-Logo.svg
/dremio/dac/ui/src/art/NarwhalLogo.svg
/dremio/dac/ui/src/art/Narwhal-Logo.svg
/dremio/dac/ui/src/art/NarwhalLogoWithNameLight.svg
I didn’t work on the favicons yet but you would just find their respective paths and replace the files with your company’s favicon but use same dremio name.
Hope that helps since it avoids having to update the code itself. You can update the code and use your own names once you see the quicker approach works and you want to go further.
