Devaraj Das commented on HBASE-9435:
------------------------------------
This broke one of our internal tests. The failing command:
{noformat}
curl -H "Content-Type: application/json" --data '{"Row":{"@key":"cm93MQ==",
"Cell":
{"@column":"Y29sZmFtOmNvbA==", "$":"dmFsdWUx"}
}}' http://localhost:17000/tcreatetbl/row1/colfam:col

> Fix jersey serialization/deserialization of json objects

> Key: HBASE-9435
> URL: https://issues.apache.org/jira/browse/HBASE-9435
> Project: HBase
> Issue Type: Bug
> Components: REST
> Reporter: Francis Liu
> Assignee: Francis Liu
> Fix For: 0.98.0, 0.96.1
>
> Attachments: HBASE-9435.patch, HBASE-9435.patch
>
>
> Stargate uses the default json marshaller/unmarshaller in natural mode. In
> this mode the unmarshaller has trouble unmarshalling json instances.
> This patch fixes this issue by using jackson as the marshaller/unmarshaller
> instead.
> I've also updated all the model unit tests to test json
> serialization/deserialization. Backwards compatibilty can be verified by
> modify the test base class to use the original marshaller/unmarshaller and
> see that model tests pass.
> The patch is backward compatible except for StorageClusterStatusModel, which
> is broken anyway. It only shows one node in the liveNodes field.
