Subject [jira] [Commented] (HBASE-11004) Extend traces through FSHLog#sync
Date Wed, 23 Apr 2014 00:40:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13977667#comment-13977667

Nick Dimiduk commented on HBASE-11004:

I haven't addressed [~iwasakims]'s tracing comments yet, see my comments on RB. I'd like to
get a clean buildbot run first; additional changes to HLogPerfEval will be cosmetic.

> Changes introduced in HBASE-8755 decouple wal append from wal sync. A gap was left in
the tracing of these requests. I believe this means are spans are decoupled from the work
happening over on HDFS-5274. This ticket is to close the air-gap between threads.
