Gerrit with solr:未找到集合：更改\u打开

我使用Gerrit2.9、Zookeeper 3.4.5和Solr6.0.0（还有5.5.1和许多其他版本）。 当我尝试reindex Gerrit时，它会因错误而崩溃：

[2016-05-16 14:49:43,605] DEBUG org.apache.zookeeper.ClientCnxn : Reading reply sessionid:0x154b93571e4001f, packet:: clientPath:null serverPath:null finished:false header:: 5,4  replyHeader:: 5,1035,0  request:: '/clusterstate.json,F  response:: #7b7d,s{104,104,1463388906650,1463388906650,0,0,0,0,2,0,104}

fatal: Collection not found: changes_open

i、 e.Gerrit在Zookeeper中找不到Solr集合，但我创建了必要的集合，我从Zookeeper控制台看到：

[zk: 127.0.0.1:2181(CONNECTED) 0] ls /collections/changes_open
[leaders, state.json, leader_elect]

对于Solr和Zookeeper，我刚刚开始工作，也许我不了解一些基本原理
