Known Issues and Limitations

• Hue integration with Spark is an experimental feature.
• The Livy version is a snapshot. Livy is supported only for use with Hue. The Livy home directory is /opt/mapr/hue-livy/hue-livy-3.10.0/.
• MapR does not support the integration between Hue 3.10.0 and the following components:
  • Solr Search
  • ZooKeeper
• Integration between Hue 3.10.0 and Sentry 1.6 is supported on secure clusters that use Kerberos authentication, but it is not supported on secure clusters that use MapR-SASL authentication.
• MapR-18668: Hue does not work on RedHat 7 / CentOS 7 / SuSE 12 when it is configured to use a MySQL database. When this issue occurs, the Control System displays the "Hue Down Alarm." Use this workaround:
  1. Run the following commands to install Maria and the Red Hat 6 compatibility library:

     yum install mariadb
     rpm -ivh --nodeps http://yum.mariadb.org/$(rpm -qa mariadb|cut -d-
     -f2)/rhel7-amd64/rpms/MariaDB-$(rpm -qa mariadb|cut -d-
     -f2)-centos7-x86_64-compat.rpm

  2. Run the following commands to reconfigure Hue:

     cd /opt/mapr/hue/hue-3.12.0/
     source ./build/env/bin/activate
     hue syncdb --noinput
     hue migrate
     deactivate                              

  3. Run the following command to restart Hue:

     maprcli node services -name hue -action restart -nodes <node_with_hue>
