Yes, I use HDP 2.6.5. Thus I still have to deal with Hive 2.
The migration to HDP 3 has been planned but in a couple of months.
So, thanks for your reply, I investigate deeper concerning the ACID support
for Orc in Hive 2.

That's the old (Hive 2) version of ACID. In the newer version (Hive 3)
there's no update, just insert and delete (update is insert + delete). If
you're working against Hive 2 what you have is what you want. If you're
working against Hive 3 you'll need the newer stuff.

Thanks Alan.
Yes, the problem is fact was that this streaming API does not handle update
and delete.
I've used native Orc files and the next step I've planned to do is the use
of ACID support as described here: https://orc.apache.org/docs/acid.html
The INSERT/UPDATE/DELETE seems to be implemented:
Have you looked at Hive's streaming ingest?
https://cwiki.apache.org/confluence/display/Hive/Streaming+Data+Ingest
It is designed for this case, though it only handles insert (not update),
so if you need updates you'd have to do the merge as you are currently
doing.

Hello,
I've just implemented a pipeline based on Apache Flink to synchronize
data between MySQL and Hive (transactional + bucketized) onto HDP
cluster. Flink jobs run on Yarn.
I've used Orc files but without ACID properties.
Then, we've created external tables on these hdfs directories that
