Hi [~ste...@apache.org], [~cnauroth],
Thanks for checking. Chris, it is typo in copy paste, sorry for the confusion.
STEP 1:
Here is the environment setup:
Hadoop-version: 2.7.2 Release
Here is the stack-trace while calling getFileStatus from test-code
programatically:
java.io.FileNotFoundException: No such file or directory:
{code}
s3a://<mask>:<mask>@dataplatform-prod-store/dev/empty
at
org.apache.hadoop.fs.s3a.S3AFileSystem.getFileStatus(S3AFileSystem.java:996)
at
com.olacabs.dp.utils.commonutils.io.S3ACustomFileSystem.main(S3ACustomFileSystem.java:29)
{code}
STEP 2: Checked out Trunk
I checked out the code and tried to work with the Trunk. However, I am hitting
into build another issue,:
{code}
Caused by: com.amazonaws.services.s3.model.AmazonS3Exception: Forbidden
(Service: Amazon S3; Status Code: 403; Error Code: 403 Forbidden; Request ID:
F8394B728D82563E), S3 Extended Request ID:

at
org.apache.hadoop.fs.s3a.S3AFileSystem.getFileStatus(S3AFileSystem.java:1414)
{code}
STEP 3: Checkout 2.7.2 and tried to patch with the "else fix"
{code}
} else if (key.isEmpty()) {
LOG.debug("Found root directory");
return new S3AFileStatus(true, true, path);
}
{code}
But looks like since the key is not empty, it is not helping here. However when
I changed to code to without this line //key = maybeAddTrailingSlash(key);
getCommonPrefixes() is non-empty.
