Also note that you can also "protect" a block from being formatted with @formatter:off and @formatter:on, avoiding a reformat on a comment for example, like in:
// Master dataframe
Dataset<Row> countyStateDf = df
.withColumn(
"countyState",
split(df.col("label"), ", "));
// I could split the column in one operation if I wanted:
// @formatter:off
// Dataset<Row> countyState0Df = df
// .withColumn(
// "state",
// split(df.col("label"), ", ").getItem(1))
// .withColumn(
// "county",
// split(df.col("label"), ", ").getItem(0));
// @formatter:on
countyStateDf.sample(.01).show(5, false);
