Hi Alex,

I created a jar including my client code (specified in manifest) and needed jar files like hadoop-20.jar, log4j.jar, commons-logging.jar and ran the application as java -cp <unjarred_location_of_above_jar> -jar above_jar needed-parameters-for-client-code.

I will explore using commons-logging in my client code.

Thanks
Pallavi

Hi Pallavi,

DFSClient uses log4j.properties for configuration.  What is your classpath?
  I need to know how exactly you invoke your program (java, hadoop script,
etc.).  The log level and appender is driven by the hadoop.root.logger
config variable.

I would also recommend to use one logging system in the code, which will be
commons-logging in this case.

Hi Alex,

Thanks for the reply. I have already created a logger (from
log4j.logger)and configured the same to log it to a file and it is logging
for all the log statements that I have in my client code. However, the
error/info logs of DFSClient are going to stdout.  The DFSClient code is
using log from commons-logging.jar. I am wondering how to redirect those
logs (which are right now going to stdout) to append to the existing logger
in client code.

Thanks
Pallavi

Hi Pallavi,

It depends what logging configuration you are using.  If it's log4j, you
need to modify (or create) log4j.properties file and point you code (via
classpath) to it.

A sample log4j.properties is in the conf directory (either apache or CDH
distributions).

Hi,

I am copying certain data from a client machine (which is not part of the
cluster) using DFSClient to HDFS. During this process, I am encountering
some issues and the error/info logs are going to stdout. Is there a way,
I
can configure the property at client side so that the error/info logs are
appended to existing log file (being created using logger at client code)
rather writing to stdout.

Thanks
Pallavi
