There is an implicit check done by HiveServer2 to make sure the user has access
to the external files. You are correct, at the HDFS level, each file permission
is individually checked.
What sort of error are you getting in hive log file? And is there any error on
the HDFS side?
Thanks

Subject: Can not create hive2 external table
Hi
In case I try to create external table and I have in example 100 000 files in
locations I point in hive DDL and Ranger authorization is enabled then I will
get different errors in hive log. Mainly they are GC timeouts.
In hdfs namenode log I can see loads of authorization rows. I think ranger is
doing check for every single file ?!
In case I disable ranger authorization for hive then it creates external table.
So - am I doing something wrong?
