Grails 2.2.1 MongoDB GORM 插件 1.2
当使用副本集运行时,我发现降低主节点会导致 java 驱动程序中出现以下无限重复的错误。
2013-09-09 16:00:19,655 [SimpleAsyncTaskExecutor-1] ERROR grails.app.services.plover.UserStreamAnalyzerService - Exception while handling status update event: org.springframework.data.mongodb.UncategorizedMongoDbException: not talking to master and retries used up; nested exception is com.mongodb.MongoException: not talking to master and retries used up
...引起:org.springframework.data.mongodb.UncategorizedMongoDbException:不与主人交谈并重试用完;嵌套异常是 com.mongodb.MongoException: not talk to master and retries used up
堆栈跟踪在这里:

我已经设置了一个本地测试环境来复制这个问题。这是配置输出:
{
"set" : "rsMesh",
"date" : ISODate("2013-09-10T01:08:20Z"),
"myState" : 2,
"syncingTo" : "macbookpro.local:27018",
"members" : [
{
"_id" : 1,
"name" : "macbookpro.local:27018",
"health" : 1,
"state" : 1,
"stateStr" : "PRIMARY",
"uptime" : 9940,
"optime" : {
"t" : 1378767619,
"i" : 5
},
"optimeDate" : ISODate("2013-09-09T23:00:19Z"),
"lastHeartbeat" : ISODate("2013-09-10T01:08:19Z"),
"lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"),
"pingMs" : 0
},
{
"_id" : 2,
"name" : "macbookpro.local:27019",
"health" : 1,
"state" : 7,
"stateStr" : "ARBITER",
"uptime" : 9914,
"lastHeartbeat" : ISODate("2013-09-10T01:08:19Z"),
"lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"),
"pingMs" : 0
},
{
"_id" : 3,
"name" : "macbookpro.local:27017",
"health" : 1,
"state" : 2,
"stateStr" : "SECONDARY",
"uptime" : 10392,
"optime" : {
"t" : 1378767619,
"i" : 5
},
"optimeDate" : ISODate("2013-09-09T23:00:19Z"),
"self" : true
}
],
"ok" : 1
}
副本集配置已根据文档在 Datasource.groovy 中设置:
grails {
mongo {
replicaSet = ["macbookpro.local:27017", "macbookpro.local:27018", "macbookpro.local:27019"]
}
}
所以我不是独立运行,副本集服务器同步正确,所有服务器运行正常。但是,如果我强制一个新服务器成为主服务器,那么所有访问似乎都会失败,就好像驱动程序没有将查询重定向到新的主服务器一样。
我错过了什么?
