When you say INSERT INTO in hive it needn't be a file append. In hive the data corresponding to a table/partition is in a directory, data is stored as one or more files within those.
AFAIK when you do insert into, a new file is created in the directory along with old files. So hdfs file append needn't come to picture here.

append, so how hive does it?
