[DISCUSS] Drop Hadoop 1 support with Flink 1.2

[rmetzger0]

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

I am totally agree with Robert. From the industry point of view, we are not using in any client Hadoop 1.x . Even in legacy system, we have already upgraded the software.

+1 to dropping Hadoop 1.x

I am fairly certain there are very few legacy Hadoop users. 2.x is heavily used at the moment.

Spark actually changed not just Hadoop but Python versions as well.

Hadoop 3 would take a while to mature so I would suggest holding off on that after it is well baked in and used.

@Robert , after sufficient folks have responded to this thread and discussed, if you could kick off a vote (if needed), then we can go ahead and get that confirmed.

Thanks for bringing it up.
