Easy Access to Web UIs of Components¶
Big data components have their own web UIs to manage their own systems. However, you cannot easily access the web UIs due to network isolation. For example, to access the HDFS web UI, you need to create an ECS to remotely log in to the web UI. This makes the UI access complex and unfriendly.
MRS provides an EIP-based secure channel for you to easily access the web UIs of components. This is more convenient than binding an EIP by yourself, and you can access the web UIs with a few clicks, avoiding the steps for logging in to a VPC, adding security group rules, and obtaining a public IP address. For the Hadoop, Spark, HBase, and Hue components in analysis clusters and the Storm component in streaming clusters, you can quickly access their web UIs from the entries on Manager.
