Subject [jira] Commented: (HADOOP-5058) Add late initialization to the chukwa log4j appender
Date Mon, 02 Mar 2009 23:49:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5058?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678163#action_12678163

Ari Rabkin commented on HADOOP-5058:

I don't understand why we need the chmod -- what are the files created as, by default?

> With the current Chukwa log4j implementation, if you define a static log4j configuration
the appender is initialized at creation time.
> This may cause some problems for example with Hadoop Audit log or Metrics context, if
the log4j properties are statically defined then a userX running an hadoop command will trigger
a permission denied exception since the appender will try to initialize itself and therefore
try to create a file under userX ownership for each appender even if not data is going to
be written to it.
> The goal is to delay this initialization until the first message is actually written
to that log so this kind of issue could easily be avoided.
