Known Issues and Limitations

  • MapR does not support the integration between Hue 3.9.0 and the following components:
    • Sentry 1.4
    • Solr Search
    • ZooKeeper
  • Integration between Hue 3.9.0 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.
  • Spark is available as a beta feature. R with Spark 1.3.1 and 1.4.1 is not supported.
  • Hive SQL only works with Hive 1.2 and Oozie 4.2.0.
  • MAPR-20358: Hive job from Job Designer examples fail on YARN mode without the 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." 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 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 commands to reconfigure Hue:
      cd /opt/mapr/hue/hue-3.12.0/
      source ./build/env/bin/activate
      hue syncdb --noinput
      hue migrate
      deactivate                              
    4. Run the following command to restart Hue:
      maprcli node services -name hue -action restart -nodes <node_with_hue>
