Re: [DISCUSS] Drop legacy hadoop support at the 2.0 release
cool, thanks all! to sum up the discussion: HBase 2.0 will have 2.6.1+ and 2.7.1+ has supported hadoop version. (hadoop 3.x support will be decided later, since work is still going on) HBASE-16884 - updates the supported version map in the docs, with the 2.6.1+ and 2.7.1+ support for 2.0 HBASE-16887 - fixes pre-commit to run with 2.6.1+, 2.7.1+, 3.0 on master (hbase 2.0) and 2.4.0+, 2.5.0+, 2.6.1+, 2.7.1+ on other branches.

Re: [DISCUSS] Drop legacy hadoop support at the 2.0 release
OK, seems no objection. I will file a issue to modify the hadoop version support matrix. And I think we also need to change the hadoopcheck versions for our precommit check?

Re: [DISCUSS] Drop legacy hadoop support at the 2.0 release
we had not decided yet AFAIK. a big concern was the lack of maintenance releases on more recent Hadoop versions and the perception that 2.4 and 2.5 were the last big stable release lines. 2.6 and 2.7 have both gotten a few maintenance releases now, so maybe this isn't a concern any more?

Re: [DISCUSS] Drop legacy hadoop support at the 2.0 release
Looking at http://hadoop.apache.org/releases.html , 2.5.x hasn't got new release for almost two years.

[DISCUSS] Drop legacy hadoop support at the 2.0 release
To be specific, hadoop-2.4.x and hadoop-2.5.x. The latest releases for these two lines are about two years ago, so I think it is the time to drop the support of them when 2.0 out. Then we could drop some code in our hadoop-compat module as we may need to add some code for the incoming hadoop-3.0... Thanks.
