We setup a Hadoop-1 build sometime back and made sure a lot of breakage were fixed, but had not hooked it up to HiveQA (precommit) due to concerns of the time it would take to run these tests. It was a balance between getting faster HiveQA results for everyone and testing all the paths, even today there are many paths we don't test. So if these JIRA's are fixed, would folks be amenable to alternate testing hadoop-1 and hadoop-2 on HiveQA precommit runs and for devs to not commit further breakages of Hadoop 1.x compat, for another release? Yes I do understand its a burden to maintain hadoop-1. if you use HDP, CDH or other hadoop distro then hadoop-1.x and hive-1.2 > combination does not exist. > I think Apache is agnostic to specific vendors so should not discuss based on that, but vendors still have this combination, I know of users that use Hadoop-1 and latest Hive 1.1.
