Subject [jira] [Commented] (HADOOP-15821) Move Hadoop YARN Registry to Hadoop Registry
Date Mon, 08 Oct 2018 11:57:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15821?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16641719#comment-16641719

Steve Loughran commented on HADOOP-15821:
-----------------------------------------

thanks for addressing my initial concerns

bq. YarnRegistryAttributes: it mentions YARN entities. It looks like is using also as generic
entities.
PersistencePolicies: it has the concept of app, container, etc. This is used in the unit tests
and around.

This about when to automatically clean stuff up. If the service to clean up entries in the
RM is still in yarn code, it can live there, maybe, or we just leave as is. It's yarn concepts,
yes, but can be ignored elsewhere: it's not YARN code

> Currently, Hadoop YARN Registry is in YARN. However, this can be used by other parts
of the project (e.g., HDFS). In addition, it does not have any real dependency to YARN.
> We should move it into commons and make it Hadoop Registry.
