> suppose we have non-acid table with some data
> An insert op starts (long running)  (with hive.txn.strict.locking.mode=false this takes
shared lock)
> An alter table runs to add (transactional=true)
> An update is run which will read the list of "original" files and assign IDs on the fly
which are written to a delta file.
> The long running insert completes.
> Another update is run which now sees a different set of "original" files and will (most
likely) assign different IDs.
> Need to make sure to mutex this
