> Thrift server returns decimal value with trailing zeros removed
> ---------------------------------------------------------------
>
> Key: LIVY-771
> URL: https://issues.apache.org/jira/browse/LIVY-771
> Project: Livy
> Issue Type: Bug
> Components: Thriftserver
> Affects Versions: 0.6.0, 0.7.0
> Reporter: Wing Yew Poon
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> I have been doing some Hive interop testing. I have a Hive table with a
> column, f_decimal decimal(5, 2).
> I run a query to select f_decimal from the table. I run this in Hive (HS2)
> through beeline, as well as in the Livy Thrift server through beeline. In the
> case of Hive, the decimal values are shown with the correct scale (2 places
> to the right of the decimal point) in all cases, while in the case of the
> Livy TS, the decimal values that have trailing zeros are shown with trailing
> zeros removed. E.g., 9.40 in Hive vs 9.4 in Livy; 713.00 in Hive vs 713 in
> Livy. (I did not actually have this in my table, but 120.00 in Hive would be
> 1.2E+2 in Livy.)
> I would argue that this is incorrect behavior (a bug). If the column type is
> decimal(5, 2), then the values should be shown with the correct scale. Also,
> the results should, where possible, be the same in Livy as in Hive.
