Answer 1

Error while starting the spark-shell on VM running on Windows: Error msg: The root scratch dir: /tmp/hive on HDFS should be writable. Permission denied

Solution: /tmp/hive is temporary directory. Only temporary files are kept in this location. No problem even if we delete this directory, will be created when required with proper permissions.

Step 1) In hdfs, Remove the /tmp/hive directory ==> "hdfs dfs -rm -r /tmp/hive"

2) At OS level too, delete the dir /tmp/hive ==> rm -rf /tmp/hive

After this, started the spark-shell and it worked fine..
