/opt/mapr/conf/cldb.conf specifies configuration parameters for the CLDB and for cluster topology.
The maximum number of read/write containers available in the CLDB cache.
The default topology for newly-created volumes.
When true, CLDB will disable all nodes with duplicate hostid, including new nodes that try to register with duplicate hostid and the existing node. Alarm NODE_ALARM_DUPLICATE_HOSTID is raised. This case requires admin intervention to correct the hostid confusion. If duplicate hostid occurs on nodes running CLDB, the cluster may fail to start in which case the alarm will not get raised, but the
Number of fileservers that must register with the CLDB before the root volume is created
The number of threads reserved for use by the CLDB.
The port on which the CLDB listens.
Enables new features added in MapR version 2.0. Used only during the upgrade process from v1.x to 2.x to control when new features become active. Once enabled, cannot be disabled.
Enables new features added in MapR version 3.0. Used only during the upgrade process from a pre-3.0 version to control when new features become active. Once enabled, cannot be disabled.
The path to a script that associates IP addresses with physical topology paths. The script takes the IP address of a single node as input and returns the physical topology that should be associated with the specified node. This association is used only at the time a node is initially added to the cluster. To change topology for nodes already in the cluster, use the
The path to a text file that associates IP addresses with physical topology paths. Each line of the text file is of format "<hostname/ip> <rack>", with the IP address or hostname of one node, followed by the topology to associate with the node. This association is used only at the time a node is initially added to the cluster. To change topology for nodes already in the cluster, use the
The port the CLDB uses for the webserver.
The nodes that are running ZooKeeper, in the format
The version of Hadoop supported by the cluster.
The CLDB JMX remote port

Only change this setting on CLDB nodes that are known to have the most recent copy of the CLDB data. Shut down all CLDB processes before changing this variable.
