After I have executed the following 3 lines
echo "export SPARK_HOME=/opt/spark" >> ~/.profile
echo "export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin" >> ~/.profile
echo "export PYSPARK_PYTHON=/usr/bin/python3" >> ~/.profile
I tried to start the master server by typing
and got the following error message
bash: start-master.sh: command not found
Thank you for any help.
