I find the same thing, especially with Hive v1.2.1 that I am currently trialling. It does lead to issues with the Metastore when trying to re-use the same Hive Table name and I find manually deleting the files in HDFS serves as a workaround.
Q. What does that have to do with the text in the Subject line in your email? From: Awhan Patnaik [mailto:aw...@spotzot.com] Sent: 04 December 2015 10:26 To: user@hive.apache.org Subject: how to search the archive Hey all! I have two questions: 1) How do I search the entire mailing list archive? 2) Sometimes I find that managed tables are not removed from HDFS even after I drop them from the Hive shell. After a "drop table foo", foo does not show up in a "show tables" listing however that table is present in HDFS. These are not external tables.
