[jira] [Commented] (PARQUET-2074) Upgrade to JDK 9+

    [ https://issues.apache.org/jira/browse/PARQUET-2074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17396113#comment-17396113 ] 

Gabor Szadovszky commented on PARQUET-2074:
-------------------------------------------

[~belugabehr], it sounds good to me but also keep in mind that switching to JDK9 and using its new capabilities would make parqet-mr incompatible with certain environments. Also, this would require a community agreement.

I would suggest bringing up this topic in the next parquet sync (Aug 24) and/or start a formal vote in the dev list.
