########## solr/solr-ref-guide/modules/deployment-guide/pages/zookeeper-ensemble.adoc: ########## @@ -589,16 +589,17 @@ The ZK connection string must list all nodes' ZK client ports (`solr_port + 1000 All three nodes must be started before the quorum can elect a leader and become operational. NOTE: On a single machine, each node needs distinct ports. Because each ZK instance also binds to `zk_client_port+1` (quorum peer) and `zk_client_port+2` (leader election), Solr ports must be spaced *at least 1001 apart* to avoid collisions. +When nodes share the same working directory, also set `solr.zookeeper.server.datadir` to a distinct path per node to avoid ZooKeeper data directory conflicts.

I think if "I want to do it somewhere special" then that leads you more towards the "I will set up my own zk ensemble"... Just thinking from the perspective of a non Solr expert... This feature is really going to be a hit among the novices to Solr who don't want to think about Cloud architectures ;-). -- This is an automated message from the Apache Git Service.
