Accumulo tserver only listens on localhost

When connecting to Accumulo (1.6.1) from a remote host, Zookeeper reports that the tservers are on localhost:9997.

Ex:

Reading reply sessionid:0x1499ab570f4001c, packet:: clientPath:null serverPath:null finished:false header:: 5,8  replyHeader:: 5,2814,0  request:: '/accumulo/eed8a68b-0ea4-46c7-a2fe-fcf6d8bd6ab5/tservers,T  response:: v{'localhost:9997}
Solution

  • Be sure to update the $ACCUMULO_HOME/conf/{masters,monitor,slaves,gc,tracers} files, as they indicate localhost by default.

    See: http://accumulo.apache.org/1.6/accumulo_user_manual.html#_cluster_specification

    11.5.3. Cluster Specification On the machine that will serve as the Accumulo master:

    1.Write the IP address or domain name of the Accumulo Master to the $ACCUMULO_HOME/conf/masters file.

    2.Write the IP addresses or domain name of the machines that will be TabletServers in $ACCUMULO_HOME/conf/slaves, one per line.

    Note that if using domain names rather than IP addresses, DNS must be configured properly for all machines participating in the cluster. DNS can be a confusing source of errors.
