Attachment: HDFS-12681.13.patch

Failing tests are due to resource exhaustion.

Updated patch to fix some checkstyle, put the findbugs suppression in the 
correct file.

Attachment: HDFS-12681.12.patch

Revised patch. This should fix the unit test failures. Also added a unit test 
to ensure {{HdfsFileStatus}} remains a superset of {{FileStatus}}.

This modifies the approach taken by HDFS-12455 by removing the 
{{setSnapShotEnabledFlag}} method and exposing {{AttrFlags}}. Frankly, I'm not 
convinced that exposing all these attribute flags in {{FileStatus}}, when most 
are only meaningful to HDFS, is valuable. The point is moot since we've already 
released it, but I hope we can eventually curtail the practice.

Chris Douglas updated HDFS-12681:
-
Attachment: HDFS-12681.11.patch

Attaching WIP patch.

This restores the types, but it also preserves a common {{HdfsFileStatus}} API 
(to avoid changing internal references excessively, and making the patch 
un-reviewable). It is now an interface that is a superset of {{FileStatus}} 
(will add a unit test for this).

In v11, {{HdfsNamedFileStatus}} is a subtype of {{FileStatus}} while 
{{HdfsLocatedFileStatus}} is a subtype of {{LocatedFileStatus}}. Anything 
user-facing already copied a subset of fields from these types, so their 
previous relationship to one another is irrelevant to compatibility (i.e., the 
fact that {{HdfsLocatedFileStatus}} is no longer a subtype of 
{{HdfsFileStatus}} doesn't matter to user code).

While v10 imposed some changes since the types were not distinct, this only 
resolves a naming collision, creating {{getBlockLocations}} and 
{{getLocatedBlocks}}. It should not be an incompatible change.

There are two other ways this could be solved.

# Lazily populate block locations by keeping a reference to the {{FileSystem}}. 
This could not only interfere with GC, but untangling how that would work with 
the {{FileSystem}} cache seems like an unnecessary exercise.
# For HDFS-7878, if {{FileStatus}} (and not {{PathHandle}}) was the token, then 
the conversion to the user-facing type could preserve metadata in the opaque 
blob. This JIRA is required because {{LocatedFileStatus}} contains only the 
fields of the base class.
