Indhumathi Muthumurugesh commented on CARBONDATA-4147:
------------------------------------------------------

1. If you have installed carbon by taking release jars from [https://carbondata.apache.org/]  , you have to wait for carbon 2.1.1 release. Issue fix will be given in this release.

2. If you have local Carbon Code setup, you can cherry-pick [https://github.com/apache/carbondata/pull/4106] and build carbon jars. In order to build carbon jars, you can refer [https://github.com/apache/carbondata/blob/master/build/README.md]

> 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
