[SPARK-13891] [SQL] [TEST] Issue Exceptions when Hitting the Max Iteration
Limit in Optimizer and Analyzer
#### What changes were proposed in this pull request?
This PR is to issue an exception in the unit tests of Spark SQL when
hitting the max iteration limit. Then, we can catch the infinite loop bugs in
Analyzer and Optimizer.
Will submit separate PRs to fix the root cause that trigger these
exceptions. Thanks!
