> Sqoop import fails creating avrodata file from the oracle source with decimal data. If the table in oracle is defined as say,
> Col1 as Decimal(12,11) , but if some data has few less digits in scale then it fails with the error as,

> also, when we dont have precision defined in Oracle ( which it takes default (38,0) i guess) it gives error as ,
> ERROR tool.ImportTool: Imported Failed: Invalid decimal precision: 0 (must be positive)
