Major Description
If schematool is run with the -verbose flag then it will print a stack trace for an exception that occurs. If a SQLException is caught during HiveSchemaTool.validateSchemaTables() then a HiveMetaException is rethrown containing the text of the SQLException. If we instead throw a HiveMetaException that wraps the SQLException then the stacktrace will help with diagnosis of issues where the SQLException contains a generic error text.
