问题描述
尊敬的会员，
我正在尝试通过Azure Portal上的HDInsight群集在Hadoop 3.6上安装Presto.在完成所有必需的配置的同时，当我部署集群时，部署过程连续失败，并且我收到"curl:(7)Failed to 连接到headnodehost端口8088:连接被拒绝.错误.我们从AmbariUI Portal收到此错误，无论何时创建HDInsight群集，我们通常都会获得此访问权限.
同样突出显示集群大小，我们正在创建具有4个工作节点D4 V2和2个头节点D12 V2的集群.几天前，我还尝试部署基本集群(不安装Presto)，并且已经成功部署，我们使用Hive查询来 从Azure Data Lake Store Gen 1获取数据.
我们正在尝试使用Presto实施相同的过程，以便为大型数据集获得更好的性能方面的一些投入.另外，我还附上下面的MS网站链接，以供您参考.
https://docs.microsoft.com/zh-cn/azure/hdinsight/hdinsight-hadoop-install-presto
请帮助我们提供相关建议/建议，以便我们可以成功地部署已安装Presto的Hadoop集群.
谢谢

Dear Members,
I am trying to install Presto on Hadoop 3.6 through HDInsight Cluster on Azure Portal. While completing all the required configurations, when I am deploying the cluster, the deployment process is continuously failed and I am getting "curl: (7) Failed to connect to headnodehost port 8088: Connection refused" Error. This error we received from AmbariUI Portal, we usually get this access, whenever we create HDInsight Cluster.
Also just highlighting Cluster sizes, we are creating cluster with 4 worker nodes D4 V2 and 2 head nodes D12 V2. I also tried to deploy basic cluster (Without Installing Presto) couple of days ago and that was successfully deployed and we used Hive query to fetch the data from Azure Data Lake Store Gen 1.
Same process we are trying to implement by using Presto so that we can get some inputs on better performance for large data sets. Also for your reference, I am attaching the below MS website link which we followed.
https://docs.microsoft.com/en-us/azure/hdinsight/hdinsight-hadoop-install-presto
Please help us out with the relevant suggestions / inputs so that we can successfully deploy Hadoop Cluster with Presto installed.
Thanks,
Rupak Agarwal
