Patches

GitHub Commit Date (YYYY-MM-DD) Comment
5a7c872 2015-10-20 MAPR-21019: When Hue submits Oozie jobs, Hue uses the default_jobtracker_host value (maprfs:/// ) instead of the jobtracker host:port address.
5f7812d 2015-09-15 MAPR-20441: Hue now automatically detects the Sqoop security settings and Hue.ini no longer contains the sqoop_conf_dir property.
569dbf5 2015-09-15 MAPR-20438: Hue is now able to connect to the ResourceManager on secure cluster because the path to ssl_cacerts in the hue.ini was corrected.
6fd0484 2015-09-07 MAPR-20357: Job browser is now able to display jobs when the cluster runs in classic mode.
ecdd711 2015-09-07 MAPR-20440: Hue now automatically detects the Hive security mechanism and therefore hive action statements in Oozie workflows no longer fail.

Known Issues

  • 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-20358: Hive job from Job Designer examples fails on YARN mode without oozie patch for 2015-10-23.
  • 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-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-3.9.0/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>
