I would create the log file manually with something like

sudo touch  /usr/local/hadoop/bin/logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

If your path is 

/usr/local/hadoop/bin/../logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

better fix as I wrote in the first line.

Then change the file's permissions:

sudo chmod 750 /usr/local/hadoop/bin/logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

and try again. It should work this time ;-)
