Yes, the import worked after creating the column family and I can see all the rows when doing scans.
But I got nothing when using Phoenix 4.0 client, so after comparing old and new tables I saw that 4.0 tables have column family name 0 instead of _0. Now as far as I know there is no way to rename a column qualifier, right? So I cant simply remove the 0 column and rename _0 to 0 right?
