[jira] [Commented] (HBASE-6449) Dapper like tracing

    [ https://issues.apache.org/jira/browse/HBASE-6449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13427481#comment-13427481 ] 

Jonathan Leavitt commented on HBASE-6449:
-----------------------------------------

Just a progress update:
The tracing library is up on [github | https://github.com/cloudera/htrace]. I am close to having it in maven central, which will make it easy to add to hbase. There are some big API changes coming soon (today?) and once those are done I will try to do the first maven release.

I am preparing an hbase patch with the hooks I have now that I will hopefully upload for review early next week.
