log4j on hama
Hello,
I need some help with log4j on Hama..I'm trying to use a logger that
writes the log messages in a log file. my log4j.properties file is :
# Define the root logger with appender file
log4j.rootLogger = DEBUG, FILE
# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
# Set the name of the file
log4j.appender.FILE.File=log.out
# Set the immediate flush to true (default)
log4j.appender.FILE.ImmediateFlush=true
# Set the threshold to debug mode
log4j.appender.FILE.Threshold=debug
# Set the append to false, overwrite
log4j.appender.FILE.Append=true
# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%m%n
I have the properties file in the same directory as my hama project, and I
include it in the files when I export my jar from eclipse.
my configuration happens on the first superstep:
BasicConfigurator.configure();
PropertyConfigurator.configure("log4j.properties");
also on the first superstep I'm trying:
log.debug("This is a debug message");
Nothing happens, the log.out file isn't created in the directory where I
ran my hama program...
Any help? How do I make this work?
Thank you in advance
Kostas

Have you checked the logs directory? The logs will be created on
{$HAMA_HOME}/logs/ and logs/tasklogs.
