Arnaud Nauwynck created ZEPPELIN-5818:
-----------------------------------------
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)
