cluster gateway resolve

Lists the gateways configured on MapR cluster that are up and running at the time that the command is issued.

Execute this command on a source MapR cluster to find out how many gateways are available for table replication to a destination MapR cluster or for indexing table data in an Elasticsearch cluster.

This command uses the following criteria to get the list:

  • If the locations of the gateways were specified with the marpcli cluster gateway set command, the maprcli cluster gateway resolve command returns the list of the gateways.

  • If the locations of the gateways were specified with a DNS record only, this command performs a DNS lookup for gateways on the specified MapR cluster and returns the list that it finds.

  • If neither of the previous methods was used to specify the locations of the gateways, this command assumes that gateways are located on the CLDB nodes configured in the mapr-clusters.conf file on the MapR cluster where the command is executed.

Note: Unresponsive gateways are not included in the list.

For more information about gateways, see MapR Gateways.


/opt/mapr/bin/maprcli cluster gateway resolve
    -dstcluster <destination cluster name>
    [ -cluster <cluster on which command to be run> ]


Parameter Description

The name of the cluster for which you want to list the available gateways.

If you are replicating table data to another MapR cluster, specify the name of that destination cluster. This destination cluster can be the source cluster if you are performing intracluster replication.

If you are indexing table data in an Elasticsearch cluster, specify the name of the source MapR cluster because that is where the gateways are located.

cluster If you are not on the source MapR cluster, provide the name of the source cluster that this command should be run on.


This example shows that only one gateway is up and running on the MapR cluster cluster1. The IP address of this gateway was found in a DNS record, as indicated by the Source field.

/opt/mapr/bin/maprcli cluster gateway resolve -dstcluster cluster1 -json
Example Output
        "timeofday":"2015-02-18 01:33:15.862 GMT+0000",
