Description

In nutch/conf is only one log4j.properties and it define:
log4j.appender.DRFA.File=${nutch.log.dir}/${nutch.log.file}
nutch.log.dir and nutch.log.file is only defined in the bin/nutch script.
In case of starting a distributed nutch instance with bin/start-all the remove tasktracker crash with:

java.io.FileNotFoundException: / (Is a directory)
cr06: at java.io.FileOutputStream.openAppend(Native Method)
cr06: at java.io.FileOutputStream.<init>(FileOutputStream.java:177)
cr06: at java.io.FileOutputStream.<init>(FileOutputStream.java:102)
cr06: at org.apache.log4j.FileAppender.setFile(FileAppender.java:289)
cr06: at org.apache.log4j.FileAppender.activateOptions(FileAppender.java:163)
cr06: at org.apache.log4j.DailyRollingFileAppender.activateOptions(DailyRollingFileAppender.java:215)
cr06: at org.apache.log4j.config.PropertySetter.activate(PropertySetter.java:256)

since the hadoop scripts used to start the tasktrackers and datanodes never define the nutch log properties but the log4j.properties require such a definition.
I suggest to leave the log4j.properties as it is in hadoop but define the hadoop property names in the bin/nutch script instead of intriduce new variable names.
