Perhaps we should move this into catalog.lookupRelation and attach the location here.

how about
try {
catalog.lookupRelation(tableIdentWithDb)
} catch {
case a: AnalysisException => u.failAnalysis(a.message)
}

Yeah, could work. This change is also causing the tests to fail, so I am revisiting it.

AnalysisException is a pretty general Exception in Spark SQL. The future refactoring might introduce bugs without trigger any test case failure.
Could we check the error messages?

@hvanhovell, how is it going? |

What changes were proposed in this pull request?
We currently have quite a few analysis exception subclasses, the problem with these is that they are not well supported throughout Spark (in pySpark for example) and that the added value is limited. This PR removes the
no such objectand thealready existsexceptions, and replaces them by a factory methods that create analysis exceptions with the required error messages.How was this patch tested?
Modified existing tests.
