In Maintenance and End of Maintenance Ecosystem Components
Pig, Flume, and Sqoop are now In Maintenance, meaning that these components will be updated only for critical security flaws and will be discontinued within six months.
Impala and Sentry have transitioned to End of Maintenance, meaning that they are removed from EEP 8.0.0 and later for core 6.2.0. No maintenance is provided for End of Maintenance components.
For more information, see Discontinued Ecosystem Components and Understand the EEP Lifecycle.
Maven Artifact Version String
Beginning with EEP 8.0.0, eep replaces mapr in the Maven artifact version string. For example:
<groupId>org.apache.hive</groupId>
<artifactId>hive</artifactId>
<version>2.3.8-mapr-2104</version><groupId>org.apache.hive</groupId>
<artifactId>hive</artifactId>
<version>2.3.9-eep-2110</version>This change applies to EEP 8.0.0 and later EEPs and does not apply to previously published Maven artifacts.
Support for Ubuntu 18.04 (But Not Ubuntu 16.04)
EEP 8.0.0 can be used with core 6.2.0 on Ubuntu 18.04 but is not supported with core 6.2.0 on Ubuntu 16.04. For a list of the operating systems that each EEP can support, see EEP Components and OS Support. For a list of the operating systems that different versions of core can support, see Operating System Support Matrix.
Maintenance EEPs
At the release of EEP 8.0.0, EEPs 7.1.1 and 6.3.5 were released as maintenance EEPs. Maintenance EEPs provide defect repair and an upgrade path for previously released EEPs.
EEP 7.1.1 is identical to EEP 7.1.0 except for changes to the monitoring (Spyglass) components. For a list of monitoring fixes , see Monitoring Release Notes.
