Subject is spark TempView thread safe
Date Fri, 31 Aug 2018 06:50:14 GMT
Hi,
we know  multiple parallel jobs can run simultaneously if they were submitted from separate
threads , now we want to reduce time cost by multiple threads in one application (sparkSession)
, I want to know is tempVIew thread safe , how about to create same tempView in one sparkSession?
