> I have hive table table1 schema of the table looks like this
> {{[CREATE TABLE table1(p_decimal1 DECIMAL(38,5)) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS TEXTFILE] }}
> and i have below value in the table
> {{row : col(p_decimal1) row1 : 12345123451234512345123.45123 }}
> in later stage if i execute
> {{select CAST(p_decimal1 AS DOUBLE) from table1; }}
> query then I am getting {{NULL}} as a output. 
> expected output should be non-null value.
