请求增加 Azure HDInsight 的配额Requesting quota increases for Azure HDInsight

CPU 内核配额有助于确保资源使用在特定 Azure 区域的所有客户之间得到公平分配。CPU core quotas help to ensure that resource usage is distributed fairly between all customers in a particular Azure region. 但是,在某些情况下,业务要求需要的群集资源量可能会超出当前配额的允许值。However, in certain cases, your business requirements might demand more cluster resources than your current quota will allow. 在这种情况下,你可以请求增加 CPU 内核配额,以便能够部署符合你数据处理要求的群集数。In such cases, you can request a CPU core quota increase so that you can deploy clusters, which match your data processing requirements.

达到配额限制时,则无法部署新群集,也无法通过添加更多工作节点来横向扩展现有群集。When you reach a quota limit, you can't deploy new clusters or scale out existing clusters by adding more worker nodes. 唯一存在配额限制的是每个订阅的区域级别的 CPU 核心配额。The only quota limit is the CPU Cores quota that exists at the region level for each subscription. 例如,订阅在中国东部地区的 CPU 内核限制可能是 30 个,而在中国东部 2 中允许的内核数又增加了 30 个。For example, your subscription may have a 30 CPU core limit in the China East region, with another 30 CPU cores allowed in the China East 2.

收集所需信息Gather required information

如果收到了提示已达到配额限制的错误消息,请使用此部分所述的过程,收集重要信息并提交增加配额请求。If you have received a error indicating that you have hit a quota limit, use the process described in this section to gather important information and submit a quota increase request.

  1. 确定所需的群集 VM 大小、规模和类型。Determine your desired cluster VM size, scale, and type.

  2. 查看订阅的当前配额容量限制。Check the current quota capacity limits of your subscription. 若要查看可用的内核数,请执行以下步骤:To check your available cores, do the following steps:

    1. 登录 Azure 门户Sign in to the Azure portal.
    2. 导航到 HDInsight 群集的“概述”页面。Navigate to the Overview page for the HDInsight cluster.
    3. 在左侧菜单上,选择“配额限制”。On the left menu, select Quota limits. 页面显示正在使用的核心数、可用核心数和总核心数。The page displays the number of cores in use, the number of available cores, and the total cores.

若要请求增加配额,请执行以下操作:To request a quota increase, do the following steps:

  1. 登录 Azure 门户Sign in to the Azure portal.

  2. 选择页面左下方的“帮助 + 支持”。Select Help + support on the bottom-left side of the page.

    “帮助和支持”按钮

  3. 选择“新建支持请求”。Select New support request.

  4. 在“新建支持请求”页面的“基本信息”选项卡下,选择以下选项 :On the New support request page, under Basics tab, select the following options:

    • “问题类型”:“服务和订阅限制(配额)”Issue type: Service and subscription limits (quotas)

    • “订阅”:想要修改的订阅Subscription: the subscription you want to modify

    • “配额类型”:HDInsightQuota type: HDInsight

      创建支持请求来增加 HDInsight 核心配额

  5. 在完成时选择“下一步:解决方案 >>”。Select Next: Solutions >>.

  6. 在“详细信息”页面,输入问题的说明,然后选择问题的严重性、首选联系方式和其他必填字段。On the Details page, enter a description of the issue, select the severity of the issue, your preferred contact method, and other required fields. 请使用下面列出的模板,确保你提供必需的信息。Use the template listed below, to ensure that you provide necessary information. 增加配额请求由 Azure 容量团队进行评估,而非 HDInsight 产品团队。Quota increase requests are evaluated by the Azure capacity team, and not by the HDInsight product team. 提供的信息越完整,请求得到批准的可能性就越大。The more complete information you provide, the more likely your request will be approved.

    I would like to request [SPECIFY DESIRED AMOUNT] on [DESIRED SKU] for [SUBSCRIPTION ID].
    
    My current quota on this subscription is [CURRENT QUOTA AMOUNT].
    
    I would like to use the extra cores for [DETAIL REASON].

  7. 在完成时选择“下一步:查看 + 创建 >>”。Select Next: Review + create >>.

  8. 在“查看 + 创建”选项卡上,选择“创建”。 On the Review + create tab, select Create.

备注

如果需要增加专用区域中的 HDInsight 核心配额,请提交允许列表请求If you need to increase the HDInsight core quota in a private region, submit a whitelist request.

可以联系支持部门来请求提高配额You can contact support to request a quota increase.

有一些配额限制是固定的。There are some fixed quota limits. 例如,单个 Azure 订阅最多可以有 10,000 个内核。For example, a single Azure subscription can have at most 10,000 cores. 有关这些限制的详细信息,请参阅 Azure 订阅和服务限制、配额与约束For details on these limits, see Azure subscription and service limits, quotas, and constraints.
