Steve Loughran updated HADOOP-12705:
------------------------------------
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.
> Upgrade Jackson 2.2.3 to 2.7.x or later

> 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.
