Subject [jira] [Commented] (HBASE-6524) Hooks for hbase tracing
Date Wed, 22 Aug 2012 19:38:42 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13439789#comment-13439789
] 

Jonathan Leavitt commented on HBASE-6524:
-----------------------------------------

So I believe the problem was that htrace was depending on hadoop 1.0.3 and there was some
problem when running it with hadoop 2 on the classpath. I removed the hadoop dependency from
htrace, so now it just uses what it needs, which is better anyways. 
The only change to the patch is depending on htrace version 1.49 as opposed to 1.48.  Should
I upload a new patch that just changes the dependency version, or one that has all of the
hooks and depends on htrace 1.49?

Also, the htrace maven repo won't be synced to maven central for another 2 hours, so I can't
upload a patch until then.
