Josh Elser commented on HIVE-18695:
-----------------------------------
bq. From the comments above, it seems like a AccumuloStorageHandler bug where
it seems to depend on PPD having been done ( I haven't done a deeper
investigation, which would be necessary to confirm).
If memory serves me, yes, the storage handler is expecting that PPD (which I'm
reading as predicate pushdown, but am honestly not positive that's what the
acronym is ;)) happens. Accumulo has a server-side computation layer in which
we take some operands from the Hive query and can push them into Accumulo for
efficiency's sake. Nothing more than filters is happening now (e.g. {{key ==
1}} and {{key == 2}} in the above query), again, if memory serves. Is there
some new kind of API which the storage handlers can look at to figure out when
PPD is going to happen (or not)? That would have serious correctness issues if
not..
[~erwaman], I'm confused on the phrasing: does HIVE-18802 apply both before and
after HIVE-15680? I think you're saying that it was an existing problem, but it
would also fix the test failures that HIVE-15680 caused?
