Hello! I have a CSV file that has the following content: C1;C2;C3 11;22;33 12;23;34 13;24;35 What is the best approach to use Spark (API, MLLib) for achieving the transpose of it? C1 11 12 13 C2 22 23 24 C3 33 34 35
I look forward for your solutions and suggestions (some Scala code will be really helpful). Thanks. Florin P.S. In reality my matrix has more than 1000 columns and more than 1 million rows.
