Steve Loughran updated MAPREDUCE-6974: -------------------------------------- Summary: Add standard configuration keys for HTrace values, propagate across to MR committers if set (was: Add standard configuration keys for Htrace values, propagate across to MR committers if set) > Add standard configuration keys for HTrace values, propagate across to MR > committers if set > ------------------------------------------------------------------------------------------- > > Key: MAPREDUCE-6974 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6974 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: job submission, performance > Affects Versions: 3.0.0-beta1 > Reporter: Steve Loughran > Priority: Minor > > HDFS &c support HTrace logging; HBase sets up spans. > What doesn't do spans is MR jobs or other frameworks with use the MR > committers. > That can be addressed by defining some standard configuration keys for HTrace > hi/low numbers, setting them in job submission, then passing them over the > wire in the Configuration, where setupJob and setupTask can extract them & > use for the tracing span. They could also add their own span for taskCommit > and jobCommit for performance measurement there. > Although the core code would be in MR, I'd propose putting the keys into > Hadoop common, > with some code in {{org.apache.hadoop.tracing.TraceUtils}}, to set it up. > That way its possible to use more broadly. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
