Fix compilation error in JdbcExecutor.executeSinkStage#759
Merged
Conversation
The executeSinkStage method introduced in apache#750 declared filterTasks and joinTasks as Collection<JdbcFilterOperator> and Collection<JdbcJoinOperator<?>> respectively, but passed them to createSqlString() which expects Collection<JdbcExecutionOperator>. Java generics are invariant so this caused a compilation failure. Fixed by widening both local variable declarations to Collection<JdbcExecutionOperator>, matching the existing pattern in the adjacent executeQueryStage method.
