Subject [jira] [Commented] (HDFS-13655) RBF: Add missing ClientProtocol APIs to RBF
Date Tue, 28 Aug 2018 18:39:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16595413#comment-16595413

Brahma Reddy Battula commented on HDFS-13655:

bq.I'm even tempted to move all of those to a single JIRA or put under an umbrella.

This could have done before we started reviewed the patch.IMO,now it's late.So let's commit
jira's which are reviewed.?

bq.For the critical issues, we can directly merge to trunk. For most of others (not critical
issues), I prefer to merge these JIRAs in the same branch and make the branch stabilised. 

This make sense to me,but no need to create the another branch, we can commit t security branch

Even I am thinking plan B, lets try close the jira's as much as possible (Only bugs), apart
from the new features like security and improvements.( Might take so much time for branch
merge which needs voting).

can we've call on this, so that we can conclude..? Or shall we discuss in mailing list..?

>          Issue Type: Improvement
>            Reporter: Xiao Chen
>            Priority: Major
> As [discussed|https://issues.apache.org/jira/browse/HDFS-12858?focusedCommentId=16500975&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16500975|#comment-16500975] with
[~elgoiri], there are some HDFS methods that does not take path as a parameter. We should
support these to work with federation.
> The ones missing are:
>  * Snapshots
>  * Storage policies
>  * Encryption zones
>  * Cache pools
> One way to reasonably have them to work with federation is to 'list' each nameservice
and concat the results. This can be done pretty much the same as {{refreshNodes()}} and
it would be a matter of querying all the subclusters and aggregate the output (e.g., {{getDatanodeReport()}}.)
