データフレームを作っただけではテーブルにはなりません。次のようにしてテーブルを登録しましょう。
swimmersJSON.createOrReplaceTempView("swimmersJSON")
ところで次のように書かれていますが、これではshowは実行されていません。.showはメソッドだと言っているだけです。実行するには.show()としなければなりません。
spark.sql("show databases").show
<bound method DataFrame.show of DataFrame[databaseName: string]>

As @pault suggested in comments, you don't need to write your own function to parse simple csv files. You can use sc.read.csv(FILEPATH).
If you want to proceed with your function as is, then you can replace
from StringIO import StringIO with from io import StringIO.
StringIO package has been replaced with io package in newer Python 3 version.

After digging into spark code, I found out that this error is actually caused from df.dropDuplicates() function because that call .match ... Do, I could apply this udf right before exporting to JSON to avoid calling dropDuplicates(), but found better solution, which was to create schema with StructType separately like the following. It’s much more organized and flexible this way · And if you JSON is much more complex that you need to twisted around then it’s much easier to just
