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")
