Converting written layout for log4j using avro to data file

["harisgx ." <ha...@gmail.com>]

Hi,

I have written a layout for log4j using avro.

http://bytescrolls.blogspot.com/2011/05/using-avro-to-serialize-logs-in-log4j.html

https://github.com/harisgx/avro-log4j

But if I want to convert the records to a avro data file in a compressed
form, in the docs it is mentioned about to use  DataFileWriteTool to read
new-line delimited JSON records.
in the method,
- run(InputStream stdin, PrintStream out, PrintStream err, List<String>
args)

args is to be non null. How do we populate the args values?

thanks

DataFileWriteTool is for command-line use.  The 'args' parameter
contains parameters supplied on the command-line.  From a Java program
you should instead use DataFileWriter.
