Preventing staging site restart during a swap

阅读更多关于 Preventing staging site restart during a swap

问题 From how I understand it, the only reason a staging site would require restart is if there exists app settings or connection strings configured as slot settings. Although this doesn't always seem to be true. One of our applications will restart regardless. I have used Powershell cmdlets to be sure that there are no slot settings "hidden" from the Portal (because apparently this is a thing). What other factors can determine whether the staging site will be restarted during a swap? (I posted

How to reset the Kudu WebJob dashboard or logging?

阅读更多关于 How to reset the Kudu WebJob dashboard or logging?

I'm trying to find details of the function executions of a particular WebJob. Unfortunately the function dashboard in Kudu is showing duplicates, exclamation marks, and no function executions for over two months. Trying to use the Azure CLI to list the WebJob's runs gives the error NotFound . The WebJob has been moved to a different web app which could be related. It doesn't matter if all of the logging history is wiped and everything reset, I would just like this working again! Any ideas?

Apache Kudu是一个为了Hadoop系统环境而打造的列存储管理器，与一般的Hadoop生态环境中的其他应用一样，具有能在通用硬件上运行、水平扩展性佳和支持高可用性操作等功能。在Kudu出现之前，Hadoop生态环境中的储存主要依赖HDFS和HBase，追求高吞吐批处理的用例中使用HDFS，追求低延时随机读取用例下用HBase，而Kudu正好能兼顾这两者。 Kudu的主要优点：快速处理OLAP（Online Analytical Processing）任务集成MapReduce、Spark和其他Hadoop环境组件与Impala高度集成，使得这成为一种高效访问交互HDFS的方法强大而灵活的统一性模型在执行同时连续随机访问时表现优异通过Cloudera Manager可以轻松管理控制高可用性，tablet server和master利用Raft Consensus算法保证节点的可用结构数据模型常见的应用场景：刚刚到达的数据就马上要被终端用户使用访问到同时支持在大量历史数据中做访问查询和某些特定实体中需要非常快响应的颗粒查询基于历史数据使用预测模型来做实时的决定和刷新要求几乎实时的流输入处理列数据存储 Columnar Data Store Kudu是一种列数据储存结构，以强类型的列（strong-type column）储存数据。高效读取
