Summary:

I see the same problem. However, in my case, this is just after installing 
74.3.3. I was previously using 74.1.0 with no problem on 10.9.2.
A forced import "zpool import -f {ID|NAME}" will mount the volume.
Every following reboot (even if you use "zpool export") I still have to do an 
explicit "zpool import -f" to mount the volume.

Details:

$ zpool status
You must be root in order to load the ZFS kext
internal error: failed to initialize ZFS library
$ sudo -s
Password:
root# zpool status
no pools available
    ====== PROMPTED that the kext is NOT signed.

  pool: splish

        disk6s2  ONLINE       0     0     0

errors: No known data errors

================================
The file system is now mounted.

Reboot.

After a reboot, the file system does not automatically mount.
A "zpool import -f splish" is required again.

root# zpool status
no pools available
root# zpool import
  pool: splish
    id: 4450072898083926272
 state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:

    splish       ONLINE
      raidz2     ONLINE
        disk4s2  ONLINE
        disk3s2  ONLINE
        disk5s2  ONLINE
        disk6s2  ONLINE
root# zpool status
no pools available
root# zpool import splish
cannot import 'splish': pool may be in use from other system
use '-f' to import anyway
root# zpool import -f splash

======================
Now, the volume is accessible again.

To see if I could workaround the problem, I thought that maybe "zpool export" 
would fix things.
Nope, "zpool import" still runs into the same problem.
"zpool import -f splish" is required to mount the volume.

Thanks for the report.
The code handling mount/umount and import/export is unchanged between 74.1.0 
(reported as working by @sbytnar in comment #1) and 74.3.3, so the change is 
probably somewhere else.
@sbytnar : Can you run our data collection script collect-maczfs-state.sh 
(http://downloads.maczfs.org/detail=21) and attach its output here and also run 
"zdb -vv -l /dev/diskXsY" (replace "diskXsY" with a device in your pool) once 
after a failed import and once after a (forced) successful import and post the 
result here?  The zdb utility should be at /usr/sbin/zdb
