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.

Structured Streaming and Hive

2017-09-29 Thread HanPan
Hi guys,

 

 I'm new to spark structured streaming. I'm using 2.1.0 and my scenario
is reading specific topic from kafka and do some data mining tasks, then
save the result dataset to hive.

 While writing data to hive, somehow it seems like not supported yet and
I tried this:



   It runs ok, but no result in hive.

 

   Any idea writing the stream result to hive?

 

Thanks

Pan
