New in This Release

Important: Note these considerations for Hue 3.10.0:
  • The Livy version is a snapshot. Livy is supported only for use with Hue.
  • MapR does not support the integration between Hue 3.10.0 and the following components:
    • Solr Search
    • Zookeeper
  • Integration between Hue 3.10.0 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.

The following are new in this release:

  • Support for Spark 2.0.1. Hue integration with Spark is an experimental feature.
  • Support for Sqoop2 1.99.7.
  • Livy is moved to its own directory:
    /opt/mapr/hue-livy/hue-livy-3.10.0/

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 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:
      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, and this library doesn't support all possible parquet formats.
