> {color:#000000}{color:#000000}{color:#000000}When tag de duplication is enabled in Apache Ranger, deleting and recreating one resource causes the tag-based policy to fail for another resource that retains the same tag in Apache Atlas. After recreating the first resource, a user with access via the tag-based policy is unexpectedly denied access to the second resource, despite the tag still being associated with it.{color}{color}{color}

> {color:#000000}{color:#000000}{color:#000000}In the {color}{color}{color:#000000}{color:#000000}dedupTags(){color}{color}{color:#000000}{color:#000000} method, if a tag’s ID is higher than the retained ID, the tag is removed from the {color}{color}{color:#000000}{color:#000000}tags{color}{color}{color:#000000}{color:#000000} map instead of updating its ID. This can invalidate the tag’s mapping for the second resource after the first resource’s deletion, breaking the policy.{color}{color}{color}
