Reynold Xin updated SPARK-9571:
-------------------------------
Description:
This is an umbrella ticket to track new expressions we are adding to
SQL/DataFrame in 1.6+.
For each new expression, we should:
1. Add a new Expression implementation in
org.apache.spark.sql.catalyst.expressions
2. If applicable, implement the code generated version (by implementing
genCode).
3. Add comprehensive unit tests (for all the data types the expressions
support).
4. If applicable, add a new function for DataFrame in
org.apache.spark.sql.functions, and python/pyspark/sql/functions.py for Python.
