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 MapR Control System (MCS) displays the "Hue Down Alarm." Use this workaround:
    1. Run the following commands to install MariaDB and the RedHat 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>
Note: Hue uses python parquet lib to read the parquet files. This library does not support all possible parquet formats.
