Hi, Guessing it's a timing issue. Once you started the query the batch 0 did not have rows to save or didn't start yet (it's a separate thread) and so spark.sql ran once and saved nothing.
You should rather use foreach writer to save results to Hive. Jacek On 29 Sep 2017 11:36 am, "HanPan" <pa...@thinkingdata.cn> wrote: > Hi guys, > > > > I’m new to spark structured streaming.
