Review Comment:
could we pass a `Context ctx` here instead of initializing the destination

Review Comment:
shouldn't we check that this was a CTAS operation? do we only need to
cleanup if an exclusive lock is enabled?

use hive_metastoreConstants.META_TABLE_LOCATION?

Review Comment:
should we catch just InterruptedException | IOException and re-throw
MetaException here?

is `!isNonNativeTable` required to exclude Iceberg tables?

would be good if we move "ifPurge" under constants as well
