> I tried to execute the SQLServer third party tests with two different SQL Server versions. With SQL Server 2014 Express edition all the tests were successful however with SQL Server 2017 Developer edition I got the following error:
> [junit] Test org.apache.sqoop.manager.sqlserver.SQLServerDatatypeImportDelimitedFileTest FAILED
>   Failure for following Test Data :
>   FLOAT
>   SCALE : null
>   PREC : null
>   TO_INSERT : 1.7976931348623157
>   DB_READBACK : 1.7976931348623155
>   HDFS_READBACK : 1.7976931348623155
>   NEG_POS_FLAG : POS
>   OFFSET : 8
>   -----------------------------------------------------------
>   Exception details :
>    expected a different string expected:<1.797693134862315[5]> but was:<1.797693134862315[7]>
> By looking at the test case I have found that it inserts 1.7976931348623157 into the database but it expects 1.7976931348623155 (the last digit is 5 instead of 7) probably because float is an approximate numeric data types on MSSQL and on earlier versions this is how it worked but.
> I suggest using a less precise float number in this test case to avoid flakyness.
