Why do I get an “Error from Spark: No more data to read.” error when testing the connection?
This is generally because “No Authentication” has been selected as the authentication mechanism instead of the default of “User Name” with a user name value of “spark”. If this does not work, please get the hive-site.xml file so we can see what authentication has been set up.
Does the driver support write-back?
No, the driver does not support writeback
