Subject [jira] [Commented] (HIVE-21820) drop database command flushing other data outside db folder
Date Sun, 02 Jun 2019 14:30:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-21820?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16853983#comment-16853983
] 

Shawn Weeks commented on HIVE-21820:
------------------------------------

I think this expected behavior. You have to include the abc.db folder in the location if you
wanted it created there. The location parameter is the entire path for the database not the
starting path.

> On running the below command to create new database:
> *create database abc location /users/hive/warehouse/project_name/;*
> here expected is, this command should create a new db folder named abc.db under project_name
directory, but with hive version 1.2.1000.2.6.3.0-235 its not creating abc.db folder.
>  
> And on running command *drop database abc;* the entire project_name directory got
deleted from HDFS. So here drop command rather than dropping just one db it deleted whole
directory and just retained meta informations in hive metastore for other dbs present in project_name directory.
