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 Control System 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>
NOTE Hue uses the python parque lib to read the parquet files. This library does not support all possible parquet formats. - Run the following commands to install MariaDB and the RedHat 6 compatibility
