[jira] [Commented] (HADOOP-9265) S3 blockstore filesystem breaks
part of the Filesystem contract
[ https://issues.apache.org/jira/browse/HADOOP-9265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13567776#comment-13567776 ]
Chris Nauroth commented on HADOOP-9265:
---------------------------------------
I applied the patch locally and verified that it fixed the new tests from HADOOP-9258.
{code}
- InputStream in = get(pathToKey(path), true);
+ String key = pathToKey(path);
+ if (isRoot(key)) {
+ return true;
+ }
+ InputStream in = get(key, true);
{code}
With this change, a query for root always resolves locally without interacting with S3. This could mask some other kinds of S3 errors, such as AccessDenied, ExpiredToken, or NoSuchBucket. Is that a concern?

> The extended tests of HADOOP-9258 show that s3 is failing things which we always expected an FS to do
> # {{getFileStatus("/")}} to return a {{FileStatus}} -currently it returns a {{FileNotFoundException}}.
> # {{rename("somedir","somedir/childdir")}} to fail. currently it returns true after deleting all the data in {{somedir/}}
