I have problem with freshly downloaded version of zeppelin and I thing there are some bugs in zeppelin running scripts:
1. I'm aware that windows is not officially supported but when bin/zeppelin.cmd is running there is no output nor logs created with any reason of failure. On environments where os permissions are limited or linux/bash layer is nor possible, it's very hard to quest the reason of fails
2. When JAVA_HOME point to some directory (mostly on windows) where catalog name contain white character like space, both .cmd and .sh scripts could not find jdk. For example for 'C:\Program Files' error is raised that 'C:\Program' doesn't exist
3. There is an issue with starting the project by lack of "org.apache.zeppelin.server.ZeppelinServer" class. The class is psychically located in "lib/zeppelin-server.jar" but looks like function "addJarInDir" doesn't exist or work incorrectly, so ZEPPELIN_SERVER, script variable cannot be located and load.
