Subject [jira] Commented: (CHUKWA-119) ChunkImpl requires ChukwaAgent class
Date Tue, 14 Apr 2009 21:23:15 GMT

    [ https://issues.apache.org/jira/browse/CHUKWA-119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12698944#action_12698944

Jerome Boulon commented on CHUKWA-119:
--------------------------------------

-1 on the patch: CHUKWA-119.patch.
Instead of doing  "c.setTags(ChukwaAgent.getTags());" all over the place, add a static block
inside the agent that will set the correct tag once.
