Removing Hadoop2 support would be a big change, I'm not very familiar with Flink, but for Spark, it requires at least Spark 3.x to support Hadoop 3, the Livy module still uses Spark 2.4.8. And Spark moved to use Hadoop Shaded client since 3.2.0, which is a quite big change for Hadoop deps management. I suppose it requires much effort to complete this task, as the community is preparing for the 0.11 release, better to postpone this change to the next release. |

I think it requires a dedicated JIRA ticket to remove Hive 1.x on Flink interpreter
