David Ho:

Background information:

I have installed a Cloudera quickstart virtual machine and run pyspark to open a jupyter notebook for practicing SparkSQL on UCSD Big Data Specialization.

The Command goes like:

`from pyspark.sql import SQLContext`
`sqlsc = SQLContext(sc)`
`df = sqlsc.read.format('jdbc') \
.option('url','jdbc:postgresql://localhost/cloudera?user=cloudera') \
.option('dbtable','gameclicks') \
.load()`

the command return the result as above, and it tells me that cloudera database does not exist.

can anyone kindly tell what leads to the problem? Is it cloudera, postgres database or wrong directory?

Appreciate any helps, thanks!
