             Summary: Actions on DataFrame created from HIVE table with newly added column throw NPE 
                 Key: SPARK-7625
                 URL: https://issues.apache.org/jira/browse/SPARK-7625
             Project: Spark
          Issue Type: Bug
            Reporter: Zhiyang Guo



We recently added a new column page_context to a hive table named "clicks", partitioned by data_date.  This leads to NPE being thrown on DataFrame created on older partitions without this column populated. For example:

val hc = new HiveContext(sc)
val clk = hc.sql("select * from clicks where data_date=20150302")
clk.show()

throws the following error msg:

java.lang.RuntimeException: cannot find field page_context from [0:log_format_number, .....]
