hadoop - Error while configuring Apache Zeppelin on Windows 10

Question

I get the following error while trying to install and configure Apache Zeppelin on Windows 10:

org.apache.zeppelin.interpreter.InterpreterException: The filename, 
directory name, or volume label syntax is incorrect

I followed below steps:
1. Downloaded and extracted folder to some location.
2. Download Java and set JAVA_HOME
3. Downloaded hadoop and set HADOOP_HOME
4. Ran zeppelin.cmd from bin folder
5. Opened zeppelin in a browser and ran example code.

I just spent a whole day trying to get Zeppelin to work on Windows 10, so I know the pain. I'll outline the steps I took so you might see what went wrong with yours:

My environment: Windows 10 with latest updates. No Spark or Hadoop installed. Java 8.

• Download zeppelin binary from https://zeppelin.apache.org/download.html and extract it somewhere you like (I have Zeppelin 0.7.3 with all-interpreters)
• Make sure you have a java jdk installed and that you have JAVA_HOME set correctly (mine is set to C:Program FilesJavajdk1.8.0_162)
• Create a folder for putting Hadoop stuff (e.g. C:Hadoophadoop-2.8.1)
• Set the HADOOP_HOME environment variable to the above folder
• Get the Hadoop binaries for windows. These can be obtained from https://github.com/steveloughran/winutils. Extract them into a 'bin' folder inside your HADOOP_HOME (I have a folder C:Hadoophadoop-2.8.1in with the binaries inside the 'bin')
• Run zeppelin.cmd
• Connect to localhost:8080 from your browser

I was having trouble because the Zeppelin page never mentions that you need to have a HADOOP_HOME and the winutils.exe binary. Relevant Zeppelin JIRA issue in https://issues.apache.org/jira/browse/ZEPPELIN-2438.

The above steps worked for me but I might have missed a couple things, so if anyone tries this and it doesn't work feel free to ask.
