-----------------------------------
Summary: Migrate to listStatusIterator in moving files
Key: HIVE-24717
URL: https://issues.apache.org/jira/browse/HIVE-24717
Project: Hive
Issue Type: Improvement
Reporter: Mustafa İman
Assignee: Mustafa İman
Hive.java has various calls to hdfs listStatus call when moving
files/directories around. These codepaths are used for insert overwrite
table/partition queries.
listStatus It is blocking call whereas listStatusIterator is backed by a
RemoteIterator and fetches pages in the background. Hive should take advantage
of that since Hadoop has implemented listStatusIterator for S3 recently
