[jira] [Created] (SPARK-8205) conditional function: nvl

Reynold Xin created SPARK-8205:
----------------------------------

             Summary: conditional function: nvl
                 Key: SPARK-8205
                 URL: https://issues.apache.org/jira/browse/SPARK-8205
             Project: Spark
          Issue Type: Sub-task
            Reporter: Reynold Xin


nvl(T value, T default_value): T

Returns default value if value is null else returns value (as of HIve 0.11).

We already have this (called Coalesce). Just need to register an alias for it in FunctionRegistry.
