Spark shell

- [Instructor] Gosh, that was a lot of concepts to go over.…I bet you're eager to get started programming.…Well here we are, in our community edition of databricks.…But, if we go to Clusters, we took so long…going over concepts that our cluster actually stopped.…So, as I said when I talked about this earlier,…one of the great things about this is…all of your objects are persistent.…So you'll remember, for example,…we added the avro-tools library,…and we added the iris table,…so those are still there, we just don't have a cluster.…

So what we're going to need to do is just recreate the cluster.…Let's call it demo again and just create the cluster,…and this'll take, oh, a minute or two,…and then once it comes up, we'll start…programming against it.…Okay, so here's my cluster.…So what I'm going to do is I'm going to go back…to databricks here, and I'm going to say new notebook,…and I'm going to call this one demo.…And it's going to be in Python, see there's our choices.…And we're going to associate it to our demo cluster.…
