> I am running the tests with isMmTable returning true for most tables (except ACID, temporary tables, views, etc.).
> Many tests will fail because of various expected issues with such an approach; however we can find issues in MM tables from other failures.
> Expected failures 
> 1) All HCat tests (cannot write MM tables via the HCat writer)
> 2) Almost all merge tests (alter .. concat is not supported).
> 3) Tests that run dfs commands with specific paths (path changes).
> 4) Truncate column (not supported).
> 5) Describe formatted will have the new table fields in the output (before merging MM with ACID).
> 6) Many tests w/explain extended - diff in partition "base file name" (path changes).
> 7) TestTxnCommands - all the conversion tests, as they check for bucket count using file lists (path changes).
> 8) HBase metastore tests cause methods are not implemented.
> 9) Some load and ExIm tests that export a table and then rely on specific path for load (path changes).
> 10) Bucket map join/etc. - diffs; disabled the optimization for MM tables due to how it accounts for buckets
> 11) rand - different results due to different sequence of processing.
> 12) many (not all i.e. not the ones with just one insert) tests that have stats output, such as file count, for obvious reasons
> 13) materialized views, not handled by design - the test check erroneously makes them "mm", no easy way to tell them apart, I don't want to plumb more stuff thru just for this test
> I'm filing jiras for some test failures that are not obvious and need an investigation later
