Description

Create a table test(a string);
Hive> create table test(key string);

Change the /user/hive/warehouse/test permission to something else other than the default, like 777.
Hive> dfs -chmod 777 /user/hive/warehouse/test;
Hive> dfs -ls -d /user/hive/warehouse/test;
drwxrwxrwx - axu wheel 68 2015-01-26 18:45 /user/hive/warehouse/test

Then truncate table test;
Hive> truncate table test;

The permission goes back to the default.
hive> dfs -ls -d /user/hive/warehouse/test;
drwxr-xr-x - axu wheel 68 2015-01-27 10:09 /user/hive/warehouse/test
