[jira] [Updated] (HIVE-24524) ShuffleHandler: upgrade to netty4

     [ https://issues.apache.org/jira/browse/HIVE-24524?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

László Bodor updated HIVE-24524:
--------------------------------
    Description: Tez already has a WIP patch for upgrading its shuffle handler to netty4. Netty4 is told to be a possible performance improvement compared to Netty3. However, the refactor is not trivial, TEZ-4157 covers that more or less (the code bases are very similar).
