When we enable security and spnego in hadoop services (HDFS Web UI, YARN Web UI, etc), all users/principal in same realm can access that service. How to restrict only users from specific OU or groups is allowed to access hadoop services. Example: only users in OU=HADOOP, DC=REALM,DC=COM can access, while users in OU=SALES,DC=REALM,DC=COM cannot access. PS: assume Active Directory is used. Thank you.

4. Increasing Number of Reducers, the Proper Way
Let's set hive.exec.reducers.bytes.per.reducer to 10 MB about 10432 It should be 10 KB not 10 MB.
