Note: Support for HDFS ACL (introduced in Apache Hadoop 2.4) is not available in the released versions of Hive. Which means, that it checks only the traditional rwx style permissions to determine if a user can write to the file system. The support for ACL is available in hive trunk HIVEHive trunk HIVE-7583, which will be available in hive Hive 0.14.
