Description

We create a carbon table

spark.sql(
s"""

CREATE TABLE carbon_table(

shortField SHORT,

intField INT,

bigintField LONG,

doubleField DOUBLE,

stringField STRING,

timestampField TIMESTAMP,

decimalField DECIMAL(18,2),

dateField DATE,

charField CHAR(5),

floatField FLOAT,

complexData ARRAY<STRING>

)

STORED BY 'carbondata'

TBLPROPERTIES('SORT_COLUMNS'='', 'DICTIONARY_INCLUDE'='dateField, charField') """.stripMargin)

Pre-aggregate create command:

spark.sql("create datamap abcaggnew on table carbon_table using 'org.apache.carbondata.datamap.AggregateDataMapHandler' as select shortField, sum(shortField) from carbon_table group by shortfield,stringField").show

when we perform query on preaggregate table using
spark.sql("select shortField, sum(shortField) from carbon_table group by shortfield,stringField").show

It shows the following error:
Exception in thread "main" org.apache.spark.sql.AnalysisException: Column does not exists in Pre Aggregate table;
