Re: Too high cardinality is not suitable for dictionary

1, in Hive, my_date is indeeded DATE type, it means which day the records
belong to
2, it is certain that the pattern for this column "mydate" is "yyyy-MM-dd",
 no "HH", "MM", "SS" at all for my_date
3, for the kylin_intermediate_* table, I'm sure the data for the column is
like "2015-03-17"
