> {noformat}
> this should throw if there is no open transaction. It should never open one.
> In general the logic seems suspect. Looks like the intent is to move all
> existing files into a delta_x_x/ when a plain table is converted to MM table.
> This seems like something that needs to be done from under an Exclusive lock
> to prevent concurrent Insert operations writing data under table/partition
> root. But this is too late to acquire locks which should be done from the
> Driver.acquireLocks() (or else have deadlock detector since acquiring them
> here would bread all-or-nothing lock acquisition semantics currently required
> w/o deadlock detector)
