Known Issues

  • MapR-20358: Hive job from Job Designer examples fails on YARN mode without Oozie patch for 2015-10-23.
  • HUE-2673: Hue displays a timeout error when a new session is not started within 60 seconds due to the lack of YARN resources.
  • 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
      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 command to create a symlink for the Cyrus SASL library:
      ln -s /usr/lib64/libsasl2.so.3.0.0 /usr/lib64/libsasl2.so.2
    3. Run the following commands to reconfigure Hue:
      source /opt/mapr/hue/hue-3.9.0/build/env/bin/activate
      /opt/mapr/hue/hue-3.9.0/build/env/bin/hue syncdb --noinput
      /opt/mapr/hue/hue-3.9.0/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>
