Hi all, pyspark is still not recognised in my jupyter notebook for instance when I do: import pyspark or anything related i get an error. I have also installed many versions of python. I try open a new notebook with different python version but still facing trouble. Here copy and paste for my .bashrc file. Please can you tell me where my error is : # .bashrc # User specific aliases and functions alias rm='rm -i' alias cp='cp -i' alias mv='mv -i' # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi export SPARK_CLASSPATH=/usr/share/java/postgresql-jdbc-8.4.704.jar export PYSPARK_DRIVER_PYTHON_OPTS="notebook" export PYSPARK_DRIVER_PYTHON=jupyter export SPARK_CLASSPATH=/usr/share/java/postgresql-jdbc-8.4.704.jar export PYSPARK_DRIVER_PYTHON_OPTS="notebook" export PYSPARK_DRIVER_PYTHON=jupyter export PATH=$PATH:/home/cloudera/anaconda3/bin # added by Anaconda3 4.0.0 installer export PATH="/home/cloudera/anaconda3/bin:$PATH" export SPARK_CLASSPATH=/usr/share/java/postgresql-jdbc-8.4.704.jar export PYSPARK_DRIVER_PYTHON_OPTS="notebook" export PYSPARK_DRIVER_PYTHON=jupyter export SPARK_CLASSPATH=/usr/share/java/postgresql-jdbc-8.4.704.jar export PYSPARK_DRIVER_PYTHON_OPTS="notebook" export PYSPARK_DRIVER_PYTHON=jupyter Thank you

I keep getting errors Cloudera: Firefox can't establish a connection to the server at localhost:8889 Two days ago things were working fine. and I don't think it is an internet problem on my end since i have been using it all day. Any idea? Thanks

Thank you for the detailed reply. I forgot to mention that my computer is 8GB RAM and I cannot use Cloudera express do to any experiment. Can i use CDH to get familiar with Hadoop, MapReduce and so on? If so, can you point me to the right direction please? Apologies for the basic question, i am new to this. Does CDH require a separate installation? I already have VM Oracle installed and ready to use

I have an 8 GB RAM and I understand that Cloudera express won't be working on my computer. Is there any alternative? How can I work with Cloudera express using my computer? Is there any way to use the Cloud to get more RAM power? Thank you for your help and guidance
