Adam Kramer commented on HIVE-446:
----------------------------------
One year later, I still want this feature.
Here's a spec:
TRUNCATE TABLE tablename;
...would delete all the data in it (simple hadoop dfs -rmr), OR drop all of the
partitions if it is a partitioned table (less simple).
TRUNCATE TABLE tablename PARTITION(ds='2011-01-01') would delete all the data
in the partition.
