Description

hive.warehouse.subdir.inherit.perms doesn't work correctly in CTAS. When it is set to true, the table created using create table .. as select.. does not inherit its parent directory's group and permission mode. It can be easily reproduced:
==
hive> dfs -ls -R /user/hive/warehouse;
drwxrwx--T - hive hive 0 2014-03-30 17:44 /user/hive/warehouse/ctas.db
drwxr-xr-x - hive hive 0 2014-03-30 17:20 /user/hive/warehouse/ctas_src_tbl
rw-rr- 3 hive hive 46059 2014-03-30 17:20 /user/hive/warehouse/ctas_src_tbl/000000_0

hive> create table ctas.test_perm as select * from ctas_src_tbl;

hive> dfs -ls -R /user/hive/warehouse;
drwxrwx--T - hive hive 0 2014-03-30 17:46 /user/hive/warehouse/ctas.db
drwxr-xr-x - hive supergroup 0 2014-03-30 17:46 /user/hive/warehouse/ctas.db/test_perm
rw-rr- 3 hive supergroup 46059 2014-03-30 17:46 /user/hive/warehouse/ctas.db/test_perm/000000_0
drwxr-xr-x - hive hive 0 2014-03-30 17:20 /user/hive/warehouse/ctas_src_tbl
rw-rr- 3 hive hive 46059 2014-03-30 17:20 /user/hive/warehouse/ctas_src_tbl/000000_0
==
The created table does not inherit its database ctas's group hive and permission mode 770, instead it takes the default group (supergroup) and permission mode (755) in hdfs
