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
