Description

Looking at git history, there were 5 commits related to updating jackson versions due to various CVEs since 2018. And it seems to get worse more recently.

File this jira to discuss the possibility of removing jackson dependency once for all. I see that jackson is deeply integrated into Hadoop codebase, so not a trivial task. However, if Hadoop is forced to make a new set of releases because of Jackson vulnerabilities, it may start to look not so costly.

At the very least, consider stripping jackson-databind coode, since that's where the majority of CVEs come from.
