Known Issues

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

    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-5.5.41-centos7_0-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 "./opt/mapr/hue/hue-3.8.1/build/env/bin/activate; /opt/mapr/hue/hue-3.8.1/build/env/bin/hue syncdb --noinput; /opt/mapr/hue/hue-3.8.1/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>
