Known Issues and Limitations

  • MAPR-18668: Hue does not work on RedHat/CentOS 7 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 MariaDB and the RedHat 6 compatibility library:
      yum install mariadb
      rpm -ivh --nodeps$(rpm -qa mariadb|cut -d-
      -f2)/rhel7-amd64/rpms/MariaDB-$(rpm -qa mariadb|cut -d-
    2. Run the following command to create a symlink for the Cyrus SASL library:
      ln -s /lib64/ /lib64/
    3. Run the following commands to reconfigure Hue:
      source /opt/mapr/hue/hue-3.10.0/build/env/bin/activate
      /opt/mapr/hue/hue-3.10.0/build/env/bin/hue syncdb --noinput
      /opt/mapr/hue/hue-3.10.0/build/env/bin/hue migrate
    4. Run the following command to restart Hue:
      maprcli node services -name hue -action restart -nodes <space separated list of hostnames>
    Note: Hue uses the python parque lib to read the parquet files. This library does not support all possible parquet formats.
  • [MAPR-2561] DB Query in Hue can't execute more than one query.
  • [HUE-6704] Hue is not able to execute Oozie snippets.
