-----------------------------------------

             Summary: bin\zeppelin.cmd on windows ... empty web page application, need unzip manually wars (and no docs saying so)
                 Key: ZEPPELIN-5818
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-5818
             Project: Zeppelin
          Issue Type: Bug
          Components: front-end
    Affects Versions: 0.10.1, 0.10.0, 0.9.0
            Reporter: Arnaud Nauwynck



calling "bin\zeppelin.cmd" on windows silently failed... the application starts, but the web page on http://localhost:8080 is empty  (with http 400 or 500 on sub pages *.js, *.css, *.png, ...)

in log, we can see

Googling this error ... nothing is found in the official installation docs, but many users complain on the same error.

Manually, done :
{noformat}

mkdir -p zeppelin-web-angular\dist
cd zeppelin-web-angular\dist
jar xf ../../zeppelin-web-angular-*.war

cd ../../

mkdir -p zeppelin-web\dist
cd zeppelin-web\dist
jar xf ../../zeppelin-web-*.war

{noformat}

 it fixed the empty web page at startup
=> expecting either to be explicitly documented in official windows install
OR (better) to be done automatically in the script (on first launch, if dir not already exists)
