My current Spark and Hadoop versions are as follows:

 spark-1.5.0-bin-hadoop2.4 versions.

I tried to start spark-shell command om my windows command prompt and this is what I get every single time.

I used Spark 1.5.2 with Hadoop 2.6 and had similar problems. Solved by doing the following steps:

  1. Download winutils.exe from the repository to some local folder, e.g. C:\hadoop\bin.

  2. Set HADOOP_HOME to C:\hadoop.

  3. Create c:\tmp\hive directory (using Windows Explorer or any other tool).

  4. Open command prompt with admin rights.

  5. Run C:\hadoop\bin\winutils.exe chmod 777 /tmp/hive

With that, I am still getting some warnings, but no ERRORs and can run Spark applications just fine.
