Subject [jira] [Commented] (HADOOP-7468) hadoop-core JAR contains a log4j.properties file
Date Fri, 05 Aug 2011 08:26:27 GMT

Steve Loughran commented on HADOOP-7468:
----------------------------------------

@Matt, No, because a live cluster gets its log4J from conf/ That's why this should not impact
any of the script-driven code, server or client -but the file in the JAR does stop any other
client app from controlling their logging.

This can break the logging of any client programs which import that JAR to do things like
DFSClient work. It should be stripped from future releases. This should not impact server-side
deployments, as the properties file in conf/ should be picked up instead.
