-------------------------------------------------------------------

There are a couple of issues, the main one being that DP directories cannot be located correctly due to some statement ID issues. I will file a followup jira, for now it looks like stmtId for MoveTask is not needed. It's set in load and import cases only, not for insert; moreover for union there are several statement IDs for the same query (one per side of the union), and the load needs to load all of them at once.

I'm also enabling mm_all test for MiniLlap

> mm_all test no longer runs on LLAP; if it's executed in LLAP, one can see that some union cases no longer work.
> Queries on partunion_mm, skew_dp_union_mm produce no results.
> I'm not sure what part of "integration" broke it.
