Subject Behavior of Hive 2837: insert into external tables should not be allowed
Date Fri, 01 Jun 2012 04:35:54 GMT
Hi folks,
I have a question regarding HIVE 2837( that deals with
disallowing external table from using insert into queries.

>From looking at the JIRA, it seems like it applies to external tables on
HDFS as well. Technically, insert into should be ok for external tables on
HDFS (and S3 as well). Seems like a storage file system level thing to
specify whether insert into is applied and implement it.

Historically, there hasn't been any real difference between creating an
external table on HDFS vs creating a managed one. However, if we disallow
insert into on external tables, that would mean that folks with external
tables on HDFS wouldn't be able to make use of insert into functionality
even though they should be able to. Do we want to allow insert into on HDFS
tables regardless of whether they are external or not?
