Answer #1

When using Spark SQL to run a query, if we get a parse exception, the query stops running at that point and does not fetch anything. The stack trace is printed on the console. The parse exception means that the sytanx of the query is not correct and there is some mistake in it. The incorrect line is printed on the console with a marker at the exact charater from where the syntax is incorrect.

It always advised to do exception handling in programs so that even in case the error occurs, the program doesn't end abruptly and displays some message to the user.
