Forced shutdown of data node immediately after completion of restart

Decided to move our cluster to 8.x and after what appeared to be a successful rolling restart of the first data node (took 90 minutes, but that's normal since each data node has 180G allocated to it), we were immediately met with it being shut down (4 seconds after it started).

Any insight or what to look at (wish ndbcluster gave better error messages)?

In the meantime, I'm going to get the data node rolled back to 7.6 (can't really just leave it offline).

Thanks
