Excluding hosts from distributed queries

To exclude hosts from distributed queries, perform these steps on each node to which you want to send queries:


  1. Navigate to the solr/conf directory.

    The default Solr conf directory location depends on the type of installation:

    • Package installations: /usr/share/dse/solr/conf

    • Tarball installations: <installation_location>/resources/solr/conf

  2. Open the exclude.hosts file, and add the list of nodes to be excluded. Separate each name with a newline character.

  3. Update the list of routing endpoints on each node by calling the JMX operation refreshEndpoints() on the com.datastax.bdp:type=search,name=Router mbean.

    For example:

    nodetool sjk mx -mc -b "com.datastax.bdp:type=search,name=Router" -op refreshEndpoints
