[ https://issues.apache.org/jira/browse/HADOOP-15774?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Íñigo Goiri updated HADOOP-15774:
---------------------------------
Summary: Leverage Hadoop Service Registry to discover Hadoop services (was: Discovery of HA servers)
> Leverage Hadoop Service Registry to discover Hadoop services
> ------------------------------------------------------------
>
> Key: HADOOP-15774
> URL: https://issues.apache.org/jira/browse/HADOOP-15774
> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Íñigo Goiri
> Priority: Major
> Attachments: Discovery Service.pdf, HadoopServiceRegistry.pdf
>
>
> Currently, Hadoop relies on configuration files to specify the servers.
> This requires maintaining these configuration files and propagating the changes.
> Hadoop should have a framework to provide discovery.
> For example, in HDFS, we could define the Namenodes in a shared location and the DNs would use the framework to find the Namenodes.
