In this Ambari article, we will learn the whole concept of Ambari Web UI in detail. We will also discuss accessing of Web UI in Ambari. <\/span><\/p>\n<p><span style=\"font-weight: 400\">However, sometimes while accessing web UI, some error occurs. So, to resolve that we will also see the Troubleshooting of Web UI. <\/span><\/p>\n<p><span style=\"font-weight: 400\">So, let\u2019s start with the introduction of Ambari Web UI.<\/span><\/p>\n<h2>Introduction to Ambari Web<\/h2>\n<p><span style=\"font-weight: 400\">Especially, for <strong>Hadoop<\/strong> management, Apache Ambari provides an easy as well as simple to use web-based UI along with RESTful APIs. Also, we can say that the web interface of Ambari, focuses to keep it simple. It becomes <strong>easy for you to<\/strong> <strong>learn Apache Ambari<\/strong>, with this easy interface. <\/span><\/p>\n<p><span style=\"font-weight: 400\">Since the main purpose of Ambari is to offer an easier way to manage as well as monitor the <strong>Hadoop ecosystem<\/strong>. In other words, to perform the cluster automation without any user interaction, Ambari APIs are made. <\/span><\/p>\n<p><span style=\"font-weight: 400\">By following the client-server architecture, a single Ambari server is usually installed on the host and also run on the host Ambari.<\/span><\/p>\n<p><span style=\"font-weight: 400\">In addition, the single point of entry to the cluster is what we call server. Basically, it runs the web UI offering the RESTful APIs of Ambari.<\/span><\/p>\n<p><span style=\"font-weight: 400\">All the REST APIs which helps in automating the operations of clusters comes with an excellent web User Interface of Ambari. Therefore, it is easy to say to manage Hadoop using web UI and providing different services to the System Administrators, Ambari is an intuitive way.<\/span><\/p>\n<h2>Accessing Ambari Web<\/h2>\n<p><span style=\"font-weight: 400\">In order to access Ambari Web:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><strong>Step 1<\/strong><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">At first, open a supported browser.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><strong>Step 2<\/strong><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Then enter the Ambari Web URL:<\/span><br \/>\n<b>http:\/\/&lt;your.ambari.server&gt;:8080<\/b><\/p>\n<p><span style=\"font-weight: 400\">Afterward, an Ambari Web login page will display in our browser:<\/span><\/p>\n<div id=\"attachment_23718\" style=\"width: 519px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/Capture1-4.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-23718\" class=\"wp-image-23718 size-full\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/Capture1-4.png\" alt=\"Ambari Web UI\" width=\"509\" height=\"338\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/Capture1-4.png 509w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/Capture1-4-150x100.png 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/Capture1-4-300x199.png 300w\" sizes=\"auto, (max-width: 509px) 100vw, 509px\" \/><\/a><p id=\"caption-attachment-23718\" class=\"wp-caption-text\">Accessing Ambari Web<\/p><\/div>\n<ul>\n<li style=\"font-weight: 400\"><strong>Step 3<\/strong><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Furthermore, enter the username as well as the password.<\/span><br \/>\n<span style=\"font-weight: 400\">However, use the default Ambari administrator account, if you are an Ambari administrator accessing the Ambari Web UI for the first time:<\/span><br \/>\n<b><\/b><\/p>\n<p><b>admin\/admin<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400\"><strong>Step 4<\/strong><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Then, click Sign In.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Make sure, you can restart it using a command line editor on the Ambari Server host machine if Ambari Server is stopped:<\/span><br \/>\n<b><br \/>\nambari-server start<\/b><\/p>\n<p>As part of the installation process, you start the Ambari Server and Ambari Web, typically.<br \/>\n<span style=\"font-weight: 400\">Moreover, from the Manage Ambari option in Ambari Web, Ambari administrators access the Ambari Admin page.<\/span><\/p>\n<div id=\"attachment_23719\" style=\"width: 154px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/Capture-2-1.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-23719\" class=\"wp-image-23719 size-full\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/07\/Capture-2-1.png\" alt=\"Ambari Web UI\" width=\"144\" height=\"148\" \/><\/a><p id=\"caption-attachment-23719\" class=\"wp-caption-text\">Accessing Ambari Web<\/p><\/div>\n<h2>Troubleshooting of Web UI<\/h2>\n<div id=\"attachment_26992\" style=\"width: 1210px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/09\/Troubleshooting-of-Ambari-Web-UI-01.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-26992\" class=\"wp-image-26992 size-full\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/09\/Troubleshooting-of-Ambari-Web-UI-01.jpg\" alt=\"Ambari WebUI\" width=\"1200\" height=\"628\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/09\/Troubleshooting-of-Ambari-Web-UI-01.jpg 1200w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/09\/Troubleshooting-of-Ambari-Web-UI-01-150x79.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/09\/Troubleshooting-of-Ambari-Web-UI-01-300x157.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/09\/Troubleshooting-of-Ambari-Web-UI-01-768x402.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2018\/09\/Troubleshooting-of-Ambari-Web-UI-01-1024x536.jpg 1024w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/a><p id=\"caption-attachment-26992\" class=\"wp-caption-text\">Troubleshooting of Ambari Web UI<\/p><\/div>\n<h3>a.
