Chris Schneider commented on NUTCH-342:
---------------------------------------
I apologize for my confusion. I had been thinking that
hadoop-env.sh was getting sourced when a Nutch command was
run; it is not. Thus, $HADOOP_LOG_DIR and $HADOOP_LOG_FILE
are not set when executing Nutch commands. For now, I think
it makes most sense for me to set NUTCH_LOG_DIR and
NUTCH_LOGFILE to the same locations as $HADOOP_LOG_DIR and
$HADOOP_LOG_FILE via .bash_profile, etc. I consider this
awkward, but am unsure about how best to address this design
problem. I'm beginning to think that NUTCH_LOGFILE should
default to something like
"nutch-$USER-$COMMAND-`hostname`.log", which
would seem more appropriate to find within the
$NUTCH_HOME/logs directory.

> If (by default) Nutch commands are going to send their
output to a file named "hadoop.log", then it
seems like the default location for this file should be the
same location where Hadoop is putting its hadoop.log file
(i.e., $HADOOP_LOG_DIR). Currently, if I set HADOOP_LOG_DIR
to a special location (via hadoop-env.sh), this has no
effect on where Nutch commands send their output.
> Some would probably suggest that I could just set
NUTCH_LOG_DIR to $HADOOP_LOG_DIR myself. I still think that
it should be defaulted this way in the nutch script.
However, I'm unaware of an elegant way to modify such Nutch
environment variables anyway. The hadoop-env.sh file
provides a convenient place to modify Hadoop environment
variables, but doing the same for Nutch environment
variables presumably requires you to modify .bash_profile or
a similar user script file (which is the way I used to
accomplish this kind of thing with Nutch 0.7).
