The recent problem is that, after HBASE-18070 had been merged, we found that the UTs from the backup module are flaky, but no one knows this feature well so it is not easy to fix the UTs. And since this feature has not been officially released yet, so if no one wants to maintain it, we will see if it is possible to just purge this feature from the code base, or move it to other sub repos. > > > > For me, I suspect that the backup feature could be done more separately > > with the main cluster.
