Description

Hi Team ,

 

We are working on a POC where we are using carbon 2.1.0.

We have created below tables,  MV :

create table if not exists fact_365_1_eutrancell_21 (ts timestamp, metric STRING, tags_id STRING, value DOUBLE) partitioned by (ts2 timestamp) stored as carbondata TBLPROPERTIES ('SORT_COLUMNS'='metric')

create materialized view if not exists fact_365_1_eutrancell_21_30_minute as select tags_id ,metric ,ts2, timeseries(ts,'thirty_minute') as ts,sum(value),avg(value),min(value),max(value) from fact_365_1_eutrancell_21 group by metric, tags_id, timeseries(ts,'thirty_minute') ,ts2

 

When i try to insert data into above Table, below error is thrown  :

scala> carbon.sql("insert into fact_365_1_eutrancell_21 values ('2020-09-25 05:30:00','eUtranCell.HHO.X2.InterFreq.PrepAttOut','ff6cb0f7-fba0-4134-81ee-55e820574627',392.2345,'2020-09-25 05:30:00')").show()

It seems the method is converting "decimal" data type of table to a "long" data type for MV.

During value conversion it is throwing the error.

Could you please check if this is a defect / bug or let me know if i have missed something ?

Note : This was working in carbon 2.0.1
