[jira] Created: (NUTCH-156) nutch-daemon.sh should not overwrite old logs by default

nutch-daemon.sh should not overwrite old logs by default
--------------------------------------------------------

         Key: NUTCH-156
         URL: http://issues.apache.org/jira/browse/NUTCH-156
     Project: Nutch
        Type: Bug
    Versions: 0.8-dev    
 Environment: a;;
    Reporter: Paul Baclace


nutch-daemon.sh creates a log file with the name pattern 

  "$NUTCH_LOG_DIR/nutch-$NUTCH_IDENT_STRING-$command-`hostname`.log"

every time it is run.  This can overwrite a previous log without warning.  As such, it is too easy to accidently lose a log that might contain unique failure information.  

Workaround:   one must remember to put aside the old logs before restarting a daemon.

Suggested fix:
  Change the log name pattern in nutch-daemon.sh to include an ISO date:
   "$NUTCH_LOG_DIR/nutch-$NUTCH_IDENT_STRING-$command-$(hostname)-$(date '+%Y%m%dT%H%M%S').log"
