Junping Du updated HDFS-8088: ----------------------------- Target Version/s: (was: 2.8.0) > Reduce the number of HTrace spans generated by HDFS reads > --------------------------------------------------------- > > Key: HDFS-8088 > URL: https://issues.apache.org/jira/browse/HDFS-8088 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Colin P. McCabe > Assignee: Colin P. McCabe > Attachments: HDFS-8088.001.patch > > > HDFS generates too many trace spans on read right now. Every call to read() > we make generates its own span, which is not very practical for things like > HBase or Accumulo that do many such reads as part of a single operation. > Instead of tracing every call to read(), we should only trace the cases where > we refill the buffer inside a BlockReader. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
