Hi,

I have a simple class which uses log4jappender and logs a single line.

The process reports the following error and hangs.

log4j:WARN No appenders could be found for logger
(org.apache.flume.api.NettyAvroRpcClient).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for
more info.
Classpath:

log4j:ERROR Flume append() failed.
I have captured the stack trace and attaching the java class, compilation
script and test shell script.

Stack trace is available in hung_stack.log file.

Any help is greatly appreciated.
Yogi

Have you set up the appender correctly? The log4j appender class is org.apache.flume.client.log4jappender.Log4jAppender - this is what needs to go in where you specify the appender in the log4j.properties file.

Hello,

Sample provided is using the sl4j-api-1.7.2, sl4j-jdk14-1.7.2.jar, and it
is working fine.

Where as flume 1.3.1 is providing the version slf4j-api-1.6.1.jar which is
not working.

Is there any limitation that I have to use jdk14 version of the jar file?
Thanks
Yogi

Hari,

This is working with the slf4j-api-1.7.2.jar and slf4j-jdk14-1.7.2.jar, but
not working with the one which is shipped with flume.

Thanks
