Íñigo Goiri commented on HDFS-12882:
------------------------------------
[~chris.douglas], thanks for [^HDFS-12882.00.salient.txt]. It makes the review
much easier (we should do this more often :)).
My only concern is changing {{getFileInfo(String src)}} into
{{getFileInfo(String src, boolean needLocation)}} for {{ClientProtocol}}.
How incompatible is this? I guess targetting 3.1 makes this change OK.
Another option would be to keep the old method and have two paths for the same;
I don't like this path though, I would prefer to fully do the change.
What about other projects like MapReduce, any breaks there?

> HDFS-7878 added support for {{open(PathHandle)}}, but it only partially
> implemented the semantics specified in the contract (i.e., open-by-inodeID).
> HDFS should implement all permutations of the default options for
> {{PathHandle}}.
