[jira] [Created] (SPARK-4869) The variable names in IF statement of SQL doesn't resolve to its value.

Ajay created SPARK-4869:
---------------------------

             Summary: The variable names in IF statement of SQL doesn't resolve to its value. 
                 Key: SPARK-4869
                 URL: https://issues.apache.org/jira/browse/SPARK-4869
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.1.1
            Reporter: Ajay
            Priority: Blocker


We got stuck with “IF-THEN” statement in Spark SQL. As per our usecase, we have to have nested “if” statements. But, spark sql is not able to resolve the variable names in final evaluation but the literal values are working. Please fix this bug. 

This works:
sqlSC.sql("SELECT DISTINCT UNIT, PAST_DUE ,IF( PAST_DUE = 'CURRENT_MONTH', 0,1) as ROLL_BACKWARD FROM OUTER_RDD")

This doesn’t :
sqlSC.sql("SELECT DISTINCT UNIT, PAST_DUE ,IF( PAST_DUE = 'CURRENT_MONTH', 0,DAYS_30) as ROLL_BACKWARD FROM OUTER_RDD")
