Agree.

The command that creates and populates the Hive table implicitly does the import as well.
However, when that fails (which is the case in the said example), the troubleshooting suggestion
is to first do the import, and next do the "create-hive-table" only. This only provisions
the Hive metastore but does not load the data in the table, which can be manually done. The
key thing here is that if there is a problem in accessing Hive or doing import, it will likely
show up in one of these two steps. I will make this explicit in the document.

Agree.
