Why does spark-shell fail with "The root scratch dir: /tmp/hive on HDFS should be writable."?
As per the error message:
Caused by: java.lang.RuntimeException: The root scratch dir: /tmp/hive on HDFS should be writable. Current permissions are: ---------
at org.apache.hadoop.hive.ql.session.SessionState.createRootHDFSDir(SessionState.java:612)
at org.apache.hadoop.hive.ql.session.SessionState.createSessionDirs(SessionState.java:554)
at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:508)

You should change the permissions of C:\tmp\hive
directory as follows:
winutils.exe chmod -R 777 C:\tmp\hive
