Jianguo Tian commented on HIVE-11995:
-------------------------------------
{code:java}
// first call FileUtils.mkdir to make sure that destf directory exists, if not,
it creates
// destf with inherited permissions
boolean destfExist = FileUtils.mkdir(destFs, destf, true, conf);
{code}
Why did you set inheritPerms param to true in this line, it makes
hive.warehouse.subdir.inherit.perms didn't work.
If the table hdfs dir permission is 770, and I want partition dir permission is
755, so I need to set hive.warehouse.subdir.inherit.perms=false.
But it has been set to true in hard code way, so
hive.warehouse.subdir.inherit.perms=false didn't work.
How do u think about this scenario. THX!
