[jira] [Commented] (PARQUET-1173) com.fasterxml.jackson.core.jackson dependency harmonization

["Gabor Szadovszky (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PARQUET-1173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16409429#comment-16409429 ] 

Gabor Szadovszky commented on PARQUET-1173:
-------------------------------------------

I don't think we should synchronize the version of dependencies and transitive dependencies. We should upgrade to the latest {{fasterxml}} jackson instead of using the ancient {{codehaus}} one, though.
The problem is that the {{codehaus}} jackson is part of the Avro public API (see AVRO-1605). It means, we are not able to drop the {{codehaus}} dependency until Avro removes jackson from its API.

> Parquet as a whole depends on many jackson versions, also legacy release.
> there are 2 overlapping dependencies on *com.fasterxml.jackson.core* bundles:

> It would be better to have only 1 non overlapping dependency tree from jackson.
> Then other submodules of Parquet depend on old "codehaus" release. These should be harmonized as well, at least those that do not need that version to cope with other third party libraries that need the old one.
> I spotted this one.
