Updating the YARN ResourceManager configuration

If you have MapR, you must set the yarn.resourcemanager.hostname property in yarn-site.xml to the fully-qualified domain name (FQDN) of your YARN ResourceManager.

Note: This procedure isn't required if you have CDH or HDP.

The property is set to 0.0.0.0 by default. To update it, run the following command on the machine hosting MCS:

/opt/mapr/server/configure.sh -C <cldb_host>[:<cldb_port>][,<cldb_host>[:<cldb_port>]...] 
-Z <zk_host>[:<zk_port>][,<zk_host>[:<zk_port>]...] [-RM <rm_host>] [-HS <hs_host>] [-L <logfile>]
[-N <cluster_name>]

Where:

<cldb_host> and <cldb_port> are the FQDNs and ports of your container location database (CLDB) nodes
<zk_host> and <zk_port> are the FQDNs and ports of your ZooKeeper nodes
<rm_host> is the FQDN of your ResourceManager
<hs_host> is the FQDN of your HistoryServer
<logfile> is the log file configure.sh will write to
<cluster_name> is the name of your MapR cluster

For more information on updating node configuration, see configure.sh in MapR's documentation.
