Hyunsik Choi created TAJO-304:
---------------------------------
Summary: drop table command should not remove data files in default
Key: TAJO-304
URL: https://issues.apache.org/jira/browse/TAJO-304
Project: Tajo
Issue Type: Improvement
Components: catalog, master
Reporter: Hyunsik Choi
Fix For: 0.8-incubating
h3. Problem
In the current implementation, Tajo removes a data directory when a user issues
'drop table' command. But, it is very dangerous in many cases. For example,
some users may lost large data sets.
h3. Solution
In default, Tajo should not remove a data directory, and we need to add a
config property 'tajo.command.drop_table.data_removal' for those who want to
change the behavior of 'drop table'.
