Hey ShaoFeng, I think this is a bug in the UI... in ResourceStateSpec#getResourceStateTable , we should check the rebalance mode, and use the partitions from external view if FULL

Hey Shaofeng, You can try using this helper class if you want to deploy the helix-ui in a war: https://github.com/apache/helix/blob/master/helix-ui/src/main/java/org/apache/helix/ui/util/DropWizardApplicationRunner.java Since the helix-ui module is intended to be packaged and run as a shaded jar

Hey, If you're not familiar with it, Dropwizard (http://www.dropwizard.io/) is a really good Java framework for building web applications. It has basically everything you'd need to build a web application - JDBI (or Hibernate), views, authentication, etc. and leverages solid existing components (J

Hey, I put together a Helix archetype that new users can use to get started (or old users who don't want to remember everything when starting a new application...) It's available here: https://github.com/brandtg/helix-archetype You can generate like this: mvn archetype:generate \ -DarchetypeG

I've attached licenses.xml result of running "mvn license:download-licenses -f helix-ui/pom.xml" There are some with LGPL, so helix-ui is not in accordance with https://www.apache.org/legal/resolved.html#category-x It may make sense to move helix-ui to contributors/helix-ui. -Greg On Sun, Apr 1

A user interface for viewing and administering clusters

Hey, I put together a simple user interface last weekend for viewing and administering Helix clusters that may be of interest here. It can run in read-only and admin mode. In read-only mode, one can view cluster / resource state and configuration in tabular form. Mismatches in ideal state / exter

Helix IPC update

We've fleshed out the idea for Helix IPC a little more (HELIX-470), and results are fairly promising. The prototype is Netty-based, and our benchmark was able to generate ~1Gbps traffic (on network w/ 1 GigE switch), where message sizes were ~1KB. The API is simplified somewhat from the original

Add performant IPC (Helix actors)

(copied from HELIX-470) Helix is missing a high-performance way to exchange messages among resource partitions, with a user-friendly API. Currently, the Helix messaging service relies on creating many nodes in ZooKeeper, which can lead to ZooKeeper outages if messages are sent too frequently. In
