Unable to load data into hive from file on hdfs - User null does not belong to hdfs

Explorer

I am unable to load data into hive from a file that exists on hdfs using hive interactively. If I place the user in the hdfs group, this works, but, of course, grants way more privileges than I want on hdfs for a basic user.

Can interactive hive commands access HDFS without being a member of the group?

========================================================================

user@server:~$ hdfs dfs -put /home/user/test99.csv /user/user/test99.csv


user@server:~$ hive

Your user does not have permissions to write to HDFS.

Try to run the query with the user that belongs to hadoop/hdfs group.

My user has access to HDFS, but only his own space. As I mentioned in the question, I know it works when I put the regular user into the HDFS group. I do not want to do this, because it grants the user access to everyone's HDFS space, just like the hdfs user. I want to get this working without the user being a member of the hdfs group. Is this possible?
