Known Issues

  • MAPR-18668: Hue does not work on RedHat/CentOS 7 when it is configured to use a MySQL database.

    When this issue occurs, the MapR Control System (MCS) displays the "Hue Down Alarm."

    Workaround:
    1. Run the following commands to install MariaDB and the Redhat 6 compatibility library:
      yum install mariadb
      ver=$(rpm -qa mariadb|cut -d- -f2)
      rpm -ivh --nodeps http://yum.mariadb.org/$ver/rhel7-amd64/rpms/MariaDB-$ver-centos7-x86_64-compat.rpm 
    2. Run the following command to create a symlink for the Cyrus SASL library:
      ln -s /lib64/libsasl2.so.3.0.0 /lib64/libsasl2.so.2
    3. Run the following command to reconfigure Hue:
      bash -c "source /opt/mapr/hue/hue-<version>/build/env/bin/activate;
            /opt/mapr/hue/hue-<version>/build/env/bin/hue syncdb --noinput;
            /opt/mapr/hue/hue-<version>/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>
