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 https://issues.apache.org/jira/browse/HADOOP-17074 -- This message was sent by Atlassian Jira (v8.3.4#803005)
