--------------------------------------
Summary: A non-persistent partitioned region attached to a
non-persistent gateway sender throws an exception if its leader co-located
region is persistent
Key: GEODE-8366
URL: https://issues.apache.org/jira/browse/GEODE-8366
Project: Geode
Issue Type: Bug
Components: wan
Reporter: Barrett Oglesby
With this configuration:
{noformat}
<gateway-sender id="non_persistent_sender" parallel="true"
enable-persistence="false" remote-distributed-system-id="1"/>
<region name="persistent_parent" refid="PARTITION_REDUNDANT_PERSISTENT"/>
<region name="non_persistent_child" refid="PARTITION_REDUNDANT">
<region-attributes gateway-sender-ids="non_persistent_sender">
<partition-attributes colocated-with="persistent_parent"
redundant-copies="1"/>
</region-attributes>
</region>
{noformat}
An exception is thrown, and the Cache fails to start.
The error and exception are:

The ParallelGatewaySenderQueue.addShadowPartitionedRegionForUserPR method
currently compares the data policy of the input region's leader region with the
sender's persistence policy. It assumes the input region and the leader region
have the same data policy. In this scenario, that is not the case. The input
region is 'non_persistent_child' which is not persistent, and the leader region
is 'persistent_parent' which is persistent. The sender is
'non_persistent_sender' which is not persistent. So, instead of comparing the
data policy of 'non_persistent_child' to the sender which would succeed since
they are both not persistent, it compares the data policy of
'persistent_parent' to the sender which fails since one is persistent, and the
other is not.
