Steve Loughran resolved HADOOP-17134. ------------------------------------- Resolution: Won't Fix > S3AFileSystem.listLocatedStatu(file) does a LIST even with S3Guard > ------------------------------------------------------------------ > > Key: HADOOP-17134 > URL: https://issues.apache.org/jira/browse/HADOOP-17134 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3 > Affects Versions: 3.4.0 > Reporter: Steve Loughran > Assignee: Mukund Thakur > Priority: Minor > > This is minor and we may want to WONTFIX; noticed during work on directory > markers. > If you call listLocatedStatus(file) then a LIST call is always made to S3, > even when S3Guard is present and has the record to say "this is a file" > Does this matter enough to fix? > # The HADOOP-16465 work moved the list before falling back to getFileStatus > # that listing calls s3guard.listChildren(path) to list the children. > # which only returns the chlldren of a path, not a record of the path itself. > # so we get an empty list back, triggering the LIST > # its only after that LIST fails that we fall back to getFileStatus and hence > look for the actual file record. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
