我对索引的行为和Solr字段的存储属性有点困惑.

例如,如果我在Schema.xml中有以下内容

<field name="test1" type="text" indexed="false"
        stored="false" required="false" />

即使我在其中创建了包含该字段的文档并将值设置为该字段并将文档提交给Solr ,字段test1也不会存储在Solr文档中.因为我有这个stored=false属性,是否意味着该字段的值在Solr中丢失而不是持久存在？

我在默认端口8080(服务)和8081(管理员)上运行基于Dropwizard的Jersey REST服务,我需要将默认端口更改为不太常用的端口,我无法找到任何信息,请有人指点我这样做吗？

我正在尝试使用下面的配置设置一个zookeeper实例,但是开始日志表明在尝试绑定端口2181时,zookeeper正在暂停.有人请告诉我这里的问题.谢谢.

我已将Hadoop 2.3部署为单节点集群.由于YARN将资源分配为一个称为容器的单元,我怎么知道在我的单个节点集群中运行了多少个容器(通过查看日志,控制台等)？.

我找不到任何方法来确定,有人可以指导我查看正在使用的数量或容器,并希望从那里获得JVM的总数吗？

提前致谢!

我正在使用SolrJ API将文档添加到Solr 4.3核心,我注意到我在我使用的stock solrconfig中将自动提交设置为15秒,如下所示.

 <autoCommit>
   <maxTime>${solr.autoCommit.maxTime:15000}</maxTime>
   <openSearcher>false</openSearcher>
 </autoCommit>

我的未知之处在于,由于自动提交设置为true,这意味着Solr实例无论如何都会每15秒自动提交一次,因此每次向Solr添加文档时,我都不需要使用SolrJ API进行明确表示,如下所示:我的理解是正确的吗？

        httpSolrServer.add(doc1);
        httpSolrServer.commit();// Is this still needed ?

提前致谢!

我安装了CentOS的MMS代理,当我作为服务启动时,我在日志文件中看到以下错误,我已经搜索了这个错误,但找不到任何引用可以有人让我知道问题是什么.

/usr/bin/mongodb-mms-monitoring-agent: error while loading shared libraries: libsasl2.so.2: cannot open shared object file: No such file or directory

谢谢.

我有一个存储有图像的存储桶，当我使用图像的公共URL检索图像时，它将在浏览器中下载而不是在浏览器中显示图像，如何查看图像而不是下载图像。我将以下网址用于上传的图片。

https://www.googleapis.com/cn/download/storage/v1/b/image-downloader-bucket/o/a06266f6-6082-468e-92ca-f918a48533a8?generation=1455661996337000&alt=media

有人可以让我知道如何创建用于查看图像的正确URL吗？

我正在尝试使用来自Eclipse的DataFlowRunner在Windows上使用MinimalWordCount运行MinimalWordCount示例 - >在eclipse中运行为Java应用程序,它使用我的gcs存储桶的示例中的相同股票代码,但是我一直得到以下异常,有人可以告诉我这里的问题吗？

1. 我已经验证了存储桶名称是否正确.
2. 我已经在我的Windows机器上运行了gcloud init.

我找不到任何与此相关的文档。time_partitioning_type=DAY 是 BigQuery 中对表进行分区的唯一方法吗？除了日期之外，该参数还可以采用其他值吗？

我正在尝试使用单个Jersey REST服务，该服务可能返回jpeg类型或png类型的图像，原因是因为该服务只能访问并且正在返回二进制数据，并且无法确定其jpeg图像还是png图像。

如果我使用以下声明，则浏览器将显示二进制数据。

@Produces("image/*")

但是，如果我对jpeg图像使用以下内容，则会显示正确的图像。

@Produces("image/jpeg").

我想知道如何使用一个声明使浏览器识别要渲染的正确图像类型（jpeg或png）？

我使用org.apache.commons.codec.digest.DigestUtils.md5Hex() Apache-Commons-Codec来计算连接字符串的mD5,但是我得到相同字符串的不同mD5哈希码值.

我看到以下输出,我的期望是它对于给定的字符串是相同的,但看起来不是.问题是什么？

我使用以下代码生成MD5 Hashcode,我在centos平台上.

    if (StringUtils.isNotBlank(concatenatedString)) {

        concatenatedString = StringUtils.deleteWhitespace(concatenatedString);
        //System.out.println("The concatenated string is "+concatenatedString);

        md5Hash = DigestUtils.md5Hex(concatenatedString);
        //System.out.println("The mD5 hashcode is  "+md5Hash);

    }

输出:

我必须检查GCE实例的正常运行时间有哪些选择？

1. 我是否需要在监视文档中安装监视代理程序，尽管它仅提到有关在GCE实例上安装的Apache服务器的正常运行时间检查的信息，但是如果没有GCE实例本身，则如何检查GCE实例本身是否已启动？网站服务器上吗？
