Mongo java抱怨说高手不是高手

Question

我遇到了这个例外：

Caused by: com.mongodb.CommandFailureException: { "serverUsed" : "twig09.twigs:27017" , "note" : "from execCommand" , "ok" : 0.0 , "errmsg" : "not master"}
        at com.mongodb.CommandResult.getException(CommandResult.java:76) ~[stormjar.jar:?]
        at com.mongodb.CommandResult.throwOnError(CommandResult.java:140) ~[stormjar.jar:?]
        at com.mongodb.DBCollectionImpl.createIndex(DBCollectionImpl.java:399) ~[stormjar.jar:?]
        at com.mongodb.DBCollection.createIndex(DBCollection.java:597) ~[stormjar.jar:?]
        at com.mongodb.DBCollection.ensureIndex(DBCollection.java:726) ~[stormjar.jar:?]

然而，twig09是主人。

            "electionDate" : ISODate("2015-12-24T17:04:02Z"),
            "self" : true

        {
            "_id" : 1,
            "name" : "twig11.twigs:27017",
            "health" : 1,
            "state" : 2,
            "stateStr" : "SECONDARY",
            "uptime" : 9957,
            "optime" : Timestamp(1450891173, 1),
            "optimeDate" : ISODate("2015-12-23T17:19:33Z"),

            "pingMs" : 0,
            "syncingTo" : "twig09.twigs:27017"
        }
    ],
    "ok" : 1
}

这是mongo 2.6，驱动程序2.13

Mongo对象用Spring中的MongoTemplate包装。

Mongo配置了mongo.setReadPreference（ReadPreference.nearest（））;但是，我不认为这是相关的，因为createIndex（）是失败的方法。

这是一个错误吗？我错过了什么吗？
