Description

• Created a new private variable `boundTEncoder` that can be shared by multiple functions, `RDD`, `select` and `collect`.
• Replaced all the `queryExecution.analyzed` by the function call `logicalPlan`
• A few API comments are using wrong class names (e.g., `DataFrame`) or parameter names (e.g., `n`)
• A few API descriptions are wrong. (e.g., `mapPartitions`)
