> Following the S3AFileSystem integration patch in HADOOP-13651, we need to add
> retry logic.
> In HADOOP-13651, I added TODO comments in most of the places retry loops are
> needed, including:
> - open(path). If MetadataStore reflects recent create/move of file path, but
> we fail to read it from S3, retry.
> - delete(path). If deleteObject() on S3 fails, but MetadataStore shows the
> file exists, retry.
> - rename(src,dest). If source path is not visible in S3 yet, retry.
> - listFiles(). Skip for now. Not currently implemented in S3Guard. I will
> create a separate JIRA for this as it will likely require interface changes
> (i.e. prefix or subtree scan).
> We may miss some cases initially and we should do failure injection testing
> to make sure we're covered. Failure injection tests can be a separate JIRA
> to make this easier to review.
> We also need basic configuration parameters around retry policy. There
> should be a way to specify maximum retry duration, as some applications would
> prefer to receive an error eventually, than waiting indefinitely. We should
> also be keeping statistics when inconsistency is detected and we enter a
> retry loop.
