<!-- Thanks for trying to help us make Apache Druid be the best it can be! Please fill out as much of the following information as is possible (where relevant, and remove it when irrelevant) to help make the intention and scope of this PR clear in order to ease review. --> <!-- Please read the doc for contribution (https://github.com/apache/druid/blob/master/CONTRIBUTING.md) before making this PR. Also, once you open a PR, please _avoid using force pushes and rebasing_ since these make it difficult for reviewers to see what you've changed in response to their reviews. See [the 'If your pull request shows conflicts with master' section](https://github.com/apache/druid/blob/master/CONTRIBUTING.md#if-your-pull-request-shows-conflicts-with-master) for more details. --> <!-- Replace XXXX with the id of the issue fixed in this PR. Remove this section if there is no corresponding issue. Don't reference the issue in the title of this pull-request. --> <!-- If you are a committer, follow the PR action item checklist for committers: https://github.com/apache/druid/blob/master/dev/committer-instructions.md#pr-and-issue-action-item-checklist-for-committers. --> ### Description <!-- Describe the goal of this PR, what problem are you fixing. If there is a corresponding issue (referenced above), it's not necessary to repeat the description here, however, you may choose to keep one summary sentence. --> <!-- Describe your patch: what did you change in code? How did you fix the problem? --> <!-- If there are several relatively logically separate changes in this PR, create a mini-section for each of them. For example: --> Broken out from #19250 due to that PR getting too large and difficult to review. This PR focuses on improving the UX for an operator working with two of the fields in the coordinator dynamic config form via web console. These fields are the decommissioning servers field and the turbo loading servers field. Each was formerly a string array where the operator was responsible for modifying a text block basically, making sure to properly format the change and not mistype, etc. I've replaced this behavior with a new dialog within the form where the console serves up lists of historicals split by tier for you to check/uncheck to modify the underlying lists of servers. There is also search filtering and tier level select/unselect. If the list contains servers(s) not announced in the cluster, you get a warning and can click to remove them as a convenience. Note that this removes the possibility of filling in the text box with servers not in the cluster at that moment. However, this ability is not outright gone in the console, you can still click through to the raw json form and do whatever you please with the list. <!-- In each section, please describe design decisions made, including: - Choice of algorithms - Behavioral aspects. What configuration values are acceptable? How are corner cases and error conditions handled, such as when there are insufficient resources? - Class organization and design (how the logic is split between classes, inheritance, composition, design patterns) - Method organization and design (how the logic is split between methods, parameters and return types) - Naming (class, method, API, configuration, HTTP endpoint, names of emitted metrics) --> <!-- It's good to describe an alternative design (or mention an alternative name) for every design (or naming) decision point and compare the alternatives with the designs that you've implemented (or the names you've chosen) to highlight the advantages of the chosen designs and names. --> <!-- If there was a discussion of the design of the feature implemented in this PR elsewhere (e. g. a "Proposal" issue, any other issue, or a thread in the development mailing list), link to that discussion from this PR description and explain what have changed in your final design compared to your original proposal or the consensus version in the end of the discussion. If something hasn't changed since the original discussion, you can omit a detailed discussion of those aspects of the design here, perhaps apart from brief mentioning for the sake of readability of this PR description. --> <!-- Some of the aspects mentioned above may be omitted for simple and small changes. --> #### Release note <!-- Give your best effort to summarize your changes in a couple of sentences aimed toward Druid users. If your change doesn't have end user impact, you can skip this section. For tips about how to write a good release note, see [Release notes](https://github.com/apache/druid/blob/master/CONTRIBUTING.md#release-notes). --> Improve the UX for cluster operators when modifying the list of servers in decommissioning nodes and/or turbo loading nodes in the web console coordinator dynamic config form. <hr> ##### Key changed/added classes in this PR * `web-console/src/dialogs/coordinator-dynamic-config-dialog/coordinator-dynamic-config-dialog.tsx` * `web-console/src/dialogs/coordinator-dynamic-config-dialog/server-multi-select-dialog.tsx` * `web-console/src/dialogs/coordinator-dynamic-config-dialog/tiered-servers.ts` * `web-console/src/druid-models/coordinator-dynamic-config/coordinator-dynamic-config.tsx` <hr> <!-- Check the items by putting "x" in the brackets for the done things.
