   @yigress I am not sure if it is LLAP related. If you check the `orc_merge1.q` file there are three `dfs -ls` operations always following an `INSERT OVERWRITE TABLE` query. I assume that the `OVERWRITE` query rewrites the directory every time. 
   
   Before HIVE-27016:
   ```
   INSERT OVERWRITE TABLE
   dfs -ls
   -rw-r--r--
   INSERT OVERWRITE TABLE
   dfs -ls
   -rw-rw-rw-
   INSERT OVERWRITE TABLE
   dfs -ls
   -rw-rw-rw-
   ```
   
   After HIVE-27016:
   ```
   INSERT OVERWRITE TABLE
   dfs -ls
   -rw-rw-rw-
   INSERT OVERWRITE TABLE
   dfs -ls
   -rw-rw-rw-
   INSERT OVERWRITE TABLE
   dfs -ls
   -rw-rw-rw-
   ```
   Worth mentioning that even before HIVE-27016 we have directories created with `-rw-rw-rw-` just not the first time.
   
   There must be a code-path that operates with different permissions and this is definitely a bug. If someone can pinpoint the exact reason of why this happens and raise a JIRA that would be great.
   
   However, given that permission differences existed even before HIVE-27016, I will not consider HIVE-27016 as a regression so I am OK to simply update the .q.out files for the moment.
