[jira] [Commented] (HADOOP-15632) Address recent API incompatibilities in cloud storage

["Steve Loughran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-15632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16558494#comment-16558494 ] 

Steve Loughran commented on HADOOP-15632:
-----------------------------------------

HADOOP-14507 actually reverts the change in HADOOP-14135. That is: it restores the constructor args of 2.6-2.8. Which is why I wasn't worried about incompatibility there, see HADOOP-14723 for that. Looks like it isn't in branch-2 at all. If we want to reinstate the HADOOP-14135 change in trunk, we should think about adding HADOOP-14507 to branch-2 as well.

> I think these are unlikely to cause any real issues, but I had to sift through a lot of reports of binary incompatibility between Hadoop 2 and Hadoop 3 and I'd like that report to be smaller next time :)
> HADOOP-14507 removes the single-parameter constructor from 2 classes that are marked as @Public and @Stable APIs. Propose we restore the original constructors and we document that they simply don't support per-bucket configs.
> HADOOP-14935 changes getFileStatusInternal from protected to private. This differs from the proposed patch and isn't discussed in the review, so I assume it's just an accident.
