Subject [jira] [Commented] (ACCUMULO-407) Look into on the fly log4j configuration
Date Sun, 19 Feb 2012 03:40:06 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13211194#comment-13211194

David Medinets commented on ACCUMULO-407:
-----------------------------------------

Does this property file change need to be done on all nodes in the cluster? Do you think it
would be hard to have log4j read from an hdfs file? Also note that Accumulo might be running
in an environment in which the files are all 'locked down' (i.e. unchangeable). In the past,
I have written a small web interface to change the log levels. The web application writes
the log4j property file.

> For long running systems, logs may not want to be kept at the debug level 24/7.  But
there may be times where a single long query may be want to looked into without cycling the
entire systems. We think it may be possible to make log4j configurable on fly, so lets start
by looking into how difficult it will be.
