Re: Does Spark support updates or deletes on underlying Hive tables

Hi, Remember that acidity and transactional support was added to Hive 0.14 onward because of advent of ORC tables. Now Spark does not support transactions because quote "there is a piece in the execution side that needs to send heartbeats to Hive metastore saying a transaction is still alive".
