Suppose I have a large Hive table, partitioned by date. I INSERT OVERWRITE a partition while a read query is currently using that table. What happens to the read query? Assume the read query is either a Hive SQL job, or a Spark SQL job. Is whatever happens deterministic? I.E. if I repeat it exactly, will I get the same or different results? Thanks!
