Íñigo Goiri commented on HADOOP-15774:
--------------------------------------
bq. This seems like quite a big feature. Two requests. One have a proposal and
design doc. Two Please open a branch if you planning to write code for this. So
we don't get into situations like HDFS-13312.
I didn't have time to add the first comment :)
Yes, as I mentioned, I want to gather ideas in the thread and do a design doc
covering both HDFS and YARN; then we can start the branch.
Is there any other implementation that makes sense?
> Discovery of HA servers
> -----------------------
>
> Key: HADOOP-15774
> URL: https://issues.apache.org/jira/browse/HADOOP-15774
> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Íñigo Goiri
> Priority: Major
>
> 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.
