"Logistic regression models ","Logistic regression goodmodels "]



I hope get the reuslt is
["Hi I heard about Spark", "Logistic regression models]



Since the first sentence is similar to second sentence and the third sentence is similar to the 4th sentence arrorcding to Levenshtein distance:https://rosettacode.org/wiki/Levenshtein_distance



How to achieve it efficiently using spark? Because the data is 200 million, I am hesitate to do cartesian

Before we started uploading we made sure the right COM-port was selected in the Arduino IDE and that also the right type of Arduino was selected. The Arduino Mega 2260.
