Question

您好我想为我的MSSQL 2008 R2服务器编写一条河流。我已将MSSQL驱动程序和jdbc jar复制到bin / plugins / jdbc目录中。我已经在Solr中测试了MSSQL驱动程序，它运行正常。所以连接字符串是正确的。

当我启动ES服务器时，我得到了这个例外：

    org.elasticsearch.common.settings.NoClassSettingsException: Failed to load class with value [jdbc]

我的卷发看起来像那样：

    curl -XPUT http://localhost:9200/_river/documents/_meta -d '
{
    "type" : "jdbc",
    "jdbc" : {
                "driver" : "com.microsoft.sqlserver.jdbc.SQLServerDriver",
                "url" : "jdbc:sqlserver://CPCDKD3;databaseName=Sampledocs",
                "user" : "XXXX",
                "password" : "XXXX",
                "sql" : "SELECT * from Docs"
    },
    "index" : {
                "index" : "documents",
                "type" : "FieldId",
                "type" : "FieldTitle",
                "type" : "FieldCOntent"
    }
}'

好的解决了。该插件必须放入$ ES_Home \ plugins而不是$ ES_Home \ bin \ plugins

Elasticsearch 0.90与MSSQL River
