I have been debugging the hbase backend issue and with maven 3.3.9 everything works fine, but it looks like
- jenkins pre-commit is using 3.2.x
- Some of the RE folks I talked to say there are still using 3.1.1
So, after a few experiments, I see that dependency management within a profile works very well only in 3.3.9 (test classpath gets messed up in various ways in 3.2.x version of maven for some reason. changing surefire plugin version does not help either). Patching this in child poms is either hacky or not elegant.
So, removing hadoop-2 profile as we no longer support hadoop-1 and this resolves many of the 3.2.5 issues
Also saw that falcon-unit is having its own version of hadoop version (2.7.1) instead of using the parent pom version. This might be the cause of some intermittent issues people were reporting. I will create a JIRA to move falcon-unit to addons just like hivedr, hdfs-snapshot-mirroring etc that require higher component versions
