Known Issues and Limitations

  • Livy is supported only for use with Hue. The Livy home directory is /opt/mapr/hue-livy/hue-livy-3.12.0/.
  • MapR-28087: Hue Livy cannot use Hive Interpreter. To work around this issue, use cluster mode. Set livy.spark.deployMode=cluster in {LIVY_CONF}/livy.conf.
  • Data Fabric does not support the integration between Hue 3.12.0 and the following components:
    • Solr Search
    • ZooKeeper
  • Integration between Hue 3.12.0 and Sentry 1.7 is supported on secure clusters that use Kerberos authentication, but it is not supported on secure clusters that use MapR-SASL authentication.
  • MapR-18668: Hue does not work on RedHat 7 / CentOS 7 / SuSE 12 when it is configured to use a MySQL database. When this issue occurs, the Control System 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$(rpm -qa mariadb|cut -d-
      -f2)/rhel7-amd64/rpms/MariaDB-$(rpm -qa mariadb|cut -d-
    2. 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
    3. Run the following command to restart Hue:
      maprcli node services -name hue -action restart -nodes <node_with_hue>
  • MapR-2561: DB Query in Hue cannot execute more than one query.
  • Hue-6074: [notebook] Execute snippets as Oozie batch.
NOTE Hue uses python parquet lib to read the parquet files. This library does not support all possible parquet formats.
