Parameter Reference

numShards

Defaults to 1

The number of shards to hash documents to. There must be one leader per shard and each leader can have N replicas.

host

Defaults to the first local host address found

If the wrong host address is found automatically, you can override the host address with this parameter.

hostPort

Defaults to the port specified via bin/solr -p <port>, or 8983 if not specified.

The port that Solr is running on. This value is only used when -DzkRun is specified without a value (see below), to calculate the default port on which embedded ZooKeeper will run. In the solr.xml shipped with Solr, the hostPort system property is not referenced, and so is ignored. If you want to run Solr on a non-default port, use bin/solr -p <port> rather than specifying -DhostPort.

hostContext

Defaults to solr

The context path for the Solr web application.

zkRun

Defaults to localhost:<hostPort+1000>

Causes Solr to run an embedded version of ZooKeeper. Set to the address of ZooKeeper on this node; this allows us to know who you are in the list of addresses in the zkHost connect string. Use -DzkRun (with no value) to get the default value.

zkHost

No default

The host address for ZooKeeper. Usually this is a comma-separated list of addresses to each node in your ZooKeeper ensemble.

zkClientTimeout

Defaults to 15000

The time a client is allowed to not talk to ZooKeeper before its session expires.

shard

Defaults to being automatically assigned based on numShards

Specifies which shard this core acts as a replica of.
