Summary: Unnecessary file existence check causes problems with S3
Key: HADOOP-13574
URL: https://issues.apache.org/jira/browse/HADOOP-13574
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3
Reporter: Alex Zolotko
Priority: Minor
We recently got the following exception on production:
{noformat}
java.io.FileNotFoundException: Key

FileOutputCommitter.commitTask() does check that the file exists before trying
to rename it, but due to S3's relaxed consistency guarantees the following
fs.rename(taskAttemptPath, committedTaskPath) still fails.
Here's an excerpt from the Amazon S3 documentation
([https://docs.aws.amazon.com/AmazonS3/latest/dev/Introduction.html]):
{quote}
Amazon S3 Data Consistency Model
Amazon S3 provides read-after-write consistency for PUTS of new objects in your
S3 bucket in all regions with one caveat. The caveat is that if you make a HEAD
or GET request to the key name (to find if the object exists) before creating
the object, Amazon S3 provides eventual consistency for read-after-write.
{quote}
The problematic S3 object existence check, that causes S3 to fallback to
eventual consistency, is in NativeS3FileSystem.create():
{code}
if (exists(f) && !overwrite) {
throw new IOException("File already exists:"+f);
}
{code}
If the overwrite parameter is set to "true" (as in our case), calling exists(f)
is unnecessary and only "upsets" S3.
The proposed fix is switch the order of the predicates:
{code}
if (!overwrite && exists(f)) {
throw new IOException("File already exists:"+f);
}
{code}
