I think the problem is this then:
mutator.addInsertion(timeUUID, columnFamilyName, column);
I'm not sure what you're doing here, but you're using your timeUUID as
the row key, not the column name. I don't see you actually assigning
the column name so I don't know what you're putting in it. You're
getting that error message because whatever is the column name in that
column is not a UUID.
