Hi, The Apache Hadoop community has recently released the first alpha version for Hadoop 3.0.0, while we are still supporting Hadoop 1. I think its time to finally drop Hadoop 1 support in Flink.
The last minor Hadoop 1 release was in 27 June, 2014. Apache Spark dropped Hadoop 1 support with their 2.0 release in July 2016. Hadoop 2.2 was first released in October 2013, so there was enough time for users to upgrade. I added also the user@ list to the discussion to get opinions about this from there as well. Let me know what you think about this! Regards, Robert
