Ramachandran updated RANGER-3903:
---------------------------------
Description:
After going through the below code snippets in the master branch
while (iter.hasNext()) {
RangerPolicy policy = iter.next();
if (policyId.equals(policy.getId()) && (changeType ==
RangerPolicyDelta.CHANGE_TYPE_POLICY_DELETE || changeType ==
RangerPolicyDelta.CHANGE_TYPE_POLICY_UPDATE))
{ deletedPolicies.add(policy); iter.remove(); }
}
switch (changeType) {
case RangerPolicyDelta.CHANGE_TYPE_POLICY_CREATE:
{
if (CollectionUtils.isNotEmpty(deletedPolicies))
{ LOG.warn("Unexpected: found existing policy for
CHANGE_TYPE_POLICY_CREATE: " + Arrays.toString(deletedPolicies.toArray()));
}
break;
}
case RangerPolicyDelta.CHANGE_TYPE_POLICY_UPDATE:
{
if (CollectionUtils.isEmpty(deletedPolicies) ||
deletedPolicies.size() > 1)
{ LOG.warn("Unexpected: found no policy or multiple policies
for CHANGE_TYPE_POLICY_UPDATE: " + Arrays.toString(deletedPolicies.toArray()));
}
break;
}
case RangerPolicyDelta.CHANGE_TYPE_POLICY_DELETE:
{
if (CollectionUtils.isEmpty(deletedPolicies) ||
deletedPolicies.size() > 1)
{ LOG.warn("Unexpected: found no policy or multiple policies
for CHANGE_TYPE_POLICY_DELETE: " + Arrays.toString(deletedPolicies.toArray()));
}
break;
}
default:
break;
}
>From the above code, we iterate delta policies and check if this policy exists
>in the existing policy, we add that to deletePolicies list.
If a delta change type is created, we expect that it should be in the
deletedPolicies list which will not happen.
So we need to add changeType == RangerPolicyDelta.CHANGE_TYPE_POLICY_CREATE as
part of the below block of code
