log4jappender hang's
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:
.:../lib/log4j-1.2.16.jar:../lib/avro-1.7.2.jar:../lib/avro-ipc-1.7.2.jar:../lib/flume-ng-core-1.3.1.jar:../lib/flume-ng-sdk-1.3.1.jar:../lib/flume-ng-log4jappender-1.3.1.jar:../lib/jackson-core-asl-1.9.3.jar:../lib/jackson-mapper-asl-1.9.3.jar:../lib/netty-3.4.0.Final.jar:../lib/slf4j-api-1.6.1.jar:../lib/slf4j-log4j12-1.6.1.jar
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
