Recently, support for s3n was removed from Hadoop by
HADOOP-14738. All calls to s3n APIs will now throw an error:
"The s3n:// client to Amazon S3 is no longer available: please migrate to the s3a:// client"
This change impacts some Impala frontend tests that cover s3n. Some fail because they expect s3n to work. Some fail because the error message is different from the one expected. The failing tests are in these two test files:
Since this is only in a recent version of hadoop, Impala still needs to maintain support for s3n, but it needs to be able to run tests on this new version of hadoop.
