---------------------------------

             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'.
