Subject [jira] [Commented] (HDFS-12745) Ozone: XceiverClientManager should cache objects based on pipeline name
Date Tue, 28 Nov 2017 23:09:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16269652#comment-16269652

Anu Engineer commented on HDFS-12745:

[~msingh] Thanks for the update, I have been looking at this patch very closely. I think you
are absolutely correct in your assessment that the real problem is the pipeline having the
container name, I am going to take a crack at separating that. I will revisit this patch soon.

> With just the standalone pipeline, a new pipeline was created for each and every container.
> This code can be optimized so that pipelines are craeted less frequently. Caching using
pipeline names will help with Ratis clients as well.
> a) Remove Container name from Pipeline object.
> b) XceiverClientManager should cache objects based on pipeline name
> c) XceiverClient and XceiverServer should be renamed to XceiverClientStandAlone &
> d) StandAlone pipeline should have notion of re-using pipeline objects.
