             Summary: ResultSet.getDouble should not throw an exception when the underlying type is a FLOAT
                 Key: DRILL-2452
                 URL: https://issues.apache.org/jira/browse/DRILL-2452
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - JDBC
            Reporter: Rahul Challapalli
            Assignee: Daniel Barclay (Drill)


git.commit.id.abbrev=e92db23

Currently when we call ResultSet.getDouble(int) and if the underlying column's type is FLOAT, we get the below exception
{code}
org.apache.drill.exec.vector.accessor.AbstractSqlAccessor$InvalidAccessException: Requesting class of type double for an object of type FLOAT4:OPTIONAL is not allowed.
	at org.apache.drill.exec.vector.accessor.AbstractSqlAccessor.getDouble(AbstractSqlAccessor.java:62)
	at org.apache.drill.exec.vector.accessor.NullableFloat4Accessor.getDouble(NullableFloat4Accessor.java:87)
	at org.apache.drill.exec.vector.accessor.BoundCheckingAccessor.getDouble(BoundCheckingAccessor.java:73)
	at org.apache.drill.jdbc.AvaticaDrillSqlAccessor.getDouble(AvaticaDrillSqlAccessor.java:101)
	at net.hydromatic.avatica.AvaticaResultSet.getDouble(AvaticaResultSet.java:233)
{code}

According to the JDBC spec we should return the double representation of the value
