Known Issues

The HBase examples provided in Hue 3.7 will not load in HBase 0.94.x because HBase 0.94.x uses a different thrift version than Hue 3.7.
When you run Hue 3.7 with a Hadoop version that is less than 2.5.1, the Job Browser hangs if you attempt to kill running YARN applications from the Job Browser window. This issue occurs with MapR version 4.0.1 as it uses Hadoop 2.4.1.
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."
