Darrel Schneider commented on GEODE-2841:
-----------------------------------------
This is an xml parser issue.
If you changed your xml to this it will work:
{code}
<?xml version="1.0" encoding="UTF-8"?>
<cache
xmlns="http://geode.apache.org/schema/cache";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://geode.apache.org/schema/cache
http://geode.apache.org/schema/cache/cache-1.0.xsd";
version="1.0">
<region name="regionA">
<region-attributes off-heap="true" data-policy="partition"/>
</region>
</cache>
{code}
The xsd allows each region to have 0 or MORE region-attributes elements. From
my understanding of the XML parser code the last one wins. (See
org.apache.geode.internal.cache.xmlcache.CacheXmlParser.endRegionAttributes()).
I do not understand how having multiple region-attribute elements in a region
could be useful. I think instead of 0 or MORE it should have just been an
optional (0 or 1) element.
The cache element can also have region-attributes sub-elements and in that case
multiple makes sense.
I'm not sure if the cache.xsd should be changed or not some I'm changing the
component to management.

> Issue Type: Bug
> Components: management
> Reporter: Swapnil Bawaskar
>
> I defined a cache.xml as follows:
> {noformat}
> <?xml version="1.0" encoding="UTF-8"?>
> <cache
> xmlns="http://geode.apache.org/schema/cache";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xsi:schemaLocation="http://geode.apache.org/schema/cache
> http://geode.apache.org/schema/cache/cache-1.0.xsd";
> version="1.0">
> <region name="regionA">
> <region-attributes off-heap="true"/>
> <region-attributes data-policy="partition"/>
> </region>
> </cache>
> {noformat}
> But, this region is not configured for off-heap:
> {noformat}
> gfsh>describe region --name=/regionA
> ..........................................................
> Name : regionA
> Data Policy : partition
> Hosting Members : serv1
> Non-Default Attributes Shared By Hosting Members
> Type | Name | Value
> ------ | ----------- | ---------
> Region | size | 0
> | data-policy | PARTITION
> {noformat}
> When the region is created from gfsh
> {noformat}
> gfsh>create region --name=regionB --type=PARTITION --off-heap
> {noformat}
> The region is configured for off-heap
> {noformat}
> gfsh>describe region --name=/regionB
> ..........................................................
> Name : regionB
> Data Policy : partition
> Hosting Members : serv1
> Non-Default Attributes Shared By Hosting Members
> Type | Name | Value
> --------- | ---------------- | ---------
> Region | data-policy | PARTITION
> | size | 0
> | off-heap | true
> Partition | local-max-memory | 3276
> {noformat}
