在开发ds过程中遇到了关于sequential file的问题

a05120230 2013-06-18 03:29:26
我开发的job里边最后需要生成一个sequential file文件。编译运行之后,在log里发现系统有个warning,内容如下

sequential_file: When checking operator: A sequential operator cannot preserve the partitioning
of the parallel data set on input port 0. [api/operator_rep.C:3433]

这样的警告通常是什么原因造成的?又要怎么解决?

由于sequencial file 不支持分区,而之前的数据已经进行了分区,因此需要在前一个stage 的preserve partitioning 设为 clear
