> Enable Atlas HiveHook in Hive with default config and an empty Atlas DB. Fire queries fast to create tables - for e.g. by having table definitions in a file and executing with hive -f <filename>. In the hive logs, we can see exceptions that hive types are being redefined. The executor threads crash due to this exception. Sample of the exception log (will attach the full log separately):
