(This section helps Arrow developers understand the context and *why* for
this feature, in addition to the *what*)
I was using datafusion-cli to test some sql queries on a large csv (for
db-benchmark). It takes a while for the table to be created as it is a large
csv. I ran the `CREATE EXTERNAL TABLE` command twice in the same session and
got the error `Execution("The table x already exists")`. However i had to wait
the full time for IO to complete before the error showed up which i think is a
waste of time. I believe this is because we are running IO before checking if
table exists.
**Describe the solution you'd like**
A clear and concise description of what you want to happen.
We should check if a table exists before doing IO and raise the table
already exists error if it already exists.
**Describe alternatives you've considered**
A clear and concise description of any alternative solutions or features
