Adam Antal commented on YARN-9607: ---------------------------------- HADOOP-15691 got committed, working on this can be continued. > Auto-configuring rollover-size of IFile format for non-appendable filesystems > ----------------------------------------------------------------------------- > > Key: YARN-9607 > URL: https://issues.apache.org/jira/browse/YARN-9607 > Project: Hadoop YARN > Issue Type: Sub-task > Components: log-aggregation, yarn > Affects Versions: 3.3.0 > Reporter: Adam Antal > Assignee: Adam Antal > Priority: Major > Attachments: YARN-9607.001.patch, YARN-9607.002.patch > > > In YARN-9525, we made IFile format compatible with remote folders with s3a > scheme. In rolling fashioned log-aggregation IFile still fails with the > "append is not supported" error message, which is a known limitation of the > format by design. > There is a workaround though: setting the rollover size in the configuration > of the IFile format, in each rolling cycle a new aggregated log file will be > created, thus we eliminated the append from the process. Setting this config > globally would cause performance problems in the regular log-aggregation, so > I'm suggesting to enforcing this config to zero, if the scheme of the URI is > s3a (or any other non-appendable filesystem). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
