Configuring the MapR Control System

The MCS properties can be configured in the /opt/mapr/apiserver/conf/properties.cfg file:

ojai.cache.size=64
mapr.webui.https.port=8443
doc.url=https://mapr.com/docs/
proxy.zkservices=elasticsearch,opentsdb
activity.metrics.thread.pool.size=10
You can add and/or modify the following:
mapr.webui.https.port Modify the value for this property to specify the port to use to connect to MCS. The default value for this property is 8443.
requestHeaderSize Add this property and set the value for this property if the header size is more than 8KB. The default value is 8KB.
ssl.exclude-protocols Add this property and set the value for this property as shown below to force the server and client to use TLSv1.2:
ssl.exclude-protocols=SSLv3,TLSv1,TLSv1.1
Note: You must restart the apiserver for the changes to take effect. For example, run the following command to restart apiserver:
maprcli node services -action restart -name apiserver -nodes `hostname`
