Steve Loughran updated HADOOP-13203: ------------------------------------ Status: Open (was: Patch Available) > S3a: Consider reducing the number of connection aborts by setting correct > length in s3 request > ---------------------------------------------------------------------------------------------- > > Key: HADOOP-13203 > URL: https://issues.apache.org/jira/browse/HADOOP-13203 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3 > Affects Versions: 2.8.0 > Reporter: Rajesh Balamohan > Assignee: Rajesh Balamohan > Attachments: HADOOP-13203-branch-2-001.patch, > HADOOP-13203-branch-2-002.patch, HADOOP-13203-branch-2-003.patch, > HADOOP-13203-branch-2-004.patch, HADOOP-13203-branch-2-005.patch, > stream_stats.tar.gz > > > Currently file's "contentLength" is set as the "requestedStreamLen", when > invoking S3AInputStream::reopen(). As a part of lazySeek(), sometimes the > stream had to be closed and reopened. But lots of times the stream was closed > with abort() causing the internal http connection to be unusable. This incurs > lots of connection establishment cost in some jobs. It would be good to set > the correct value for the stream length to avoid connection aborts. > I will post the patch once aws tests passes in my machine. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
