[jira] [Comment Edited] (MESOS-2709) Design Master discovery
functionality for HTTP-only clients
[ https://issues.apache.org/jira/browse/MESOS-2709?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14541141#comment-14541141 ]

-----------------------------------------------------------------
Created proof of concept in Python: (zk-mesos)[https://github.com/massenz/zk-mesos]
(this is one, the simplest to implement, of several possible - but also, by its very nature, the least "pure").
Adapting this to work with Java (and, by consequence, Scala) is trivial - other languages (eg Go) complexity depends on the difficulty of binding to Google Protobufs.
Starting to write the design doc, outlining the various alternatives.

> Project: Mesos
> Issue Type: Improvement
> Components: java api
> Reporter: Marco Massenzio

> When building clients that do not bind to {{libmesos}} and only use the HTTP API (via "pure" language bindings - eg, Java-only) there is no simple way to discover the Master's IP address to connect to.
> Rather than relying on 'out-of-band' configuration mechanisms, we would like to enable the ability of interrogating the ZooKeeper ensemble to discover the Master's IP address (and, possibly, other information) to which the HTTP API requests can be addressed to.
