Release Note

We are sorry for causing pain for everyone for whom this Jackson update causes problems, but it was proving impossible to stay on the older version: too much code had moved past it, and by staying back we were limiting what Hadoop could do, and giving everyone who wanted an up to date version of Jackson a different set of problems. We've selected Jackson 2.7.8 as it fixed fix a security issue in XML parsing, yet proved compatible at the API level with the Hadoop codebase --and hopefully everything downstream.

Description

There's no rush to do this; this is just the JIRA to track versions. However, without the upgrade, things written for Jackson 2.4.4 can break ( SPARK-12807)

being Jackson, this is a potentially dangerous update.
