Kudu failed to load FS


 after the upgrade from CDH 5.11 to 5.13 one Tablet server failed to start. This one is different from the others, because it has just three data directories (and disks) but the others have four disks. In the previous version (CDH 5.11) it wasnt a problem and the configuration was splitted to two configuration groups.

Now after the upgrade the Kudu instances are all in the same group. This is interesting because the configuration still holds one override for this specific host. I tried to manually reasssing this host to a specific group but still dont want to start.
