Feature Support
- MapR supports Hive-2.1.1 on Tez-0.8.4. For more information, see Tez 0.8.4-1901 (EEP 4.1.3 and EEP 5.0.2) Release Notes.
- MapR does not support Hive on Spark, so you cannot use Spark as an execution engine for Hive. However, you can run Hive and Spark on the same cluster. You can also use Spark SQL and Drill to query Hive tables.
- MapR does not support HDFS encryption in Hive tables.
- MapR does not support HBase with Hive-2.1.1 starting from mapr-core-6.0.0.
- MapR does not support LLAP with Hive-2.1.1 as Apache Slider is not a MapR ecosystem component.
- Starting from Hive 2.1, Hive needs to run the
schematool
command as an initialization step.
New Features
- None.
Changes in Security with Default Configuration
- None.
Because hive.users.in.admin.role
and
hive.security.authorization.manager
were added to default Hive
configuration, some actions in Hive are restricted according to security best practices and
CVE-2018-11777
The new class
FallbackHiveAuthorizerFactory
will do the following to mitigate the
above-mentioned CVE-2018-11777:
- Disallow local file location in SQL statements for all except the administrator.
- Allow
set
only selected white list parameters. - Disallow
dfs
commands for all except the administrator. - Disallow
ADD JAR
statements for all except the administrator. - Disallow
COMPILE
statements for all except the administrator. - Disallow
TRANSFORM
statements.
Known Issues
- Vectorized execution is a new Hive feature that can show performance improvements in some cases and cause stability issues with others. The Hive vectorized execution feature has many bugs in Hive 2.x. It is recommended to turn off this feature at a system level and only use it for certain queries which work fine using it. You must evaluate the benefit of this feature against the potential stability issues on a case by case basis.
