Known Issues and Limitations
Note these important limitations:
- MapR does not support the integration between Hue 3.9.0 and the following components:
- Sentry 1.4
- Solr Search
- Zookeeper
- The 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:
- 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
- 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
- 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
- Run the following command to restart
Hue:
maprcli node services -name hue -action restart -nodes <space separated list of hostnames>
